Review based on a production Panasonic DMC-G2

Panasonic's G1 was not only the first product of the Micro Four Thirds standard, it was also the world's first interchangeable lens camera to turn its back on traditional optical viewfinder designs and take a more compact-camera-like live view approach. The outward appearance may have been pure DSLR, but the G1 is likely to be remembered as the camera that marked the beginning of the end for the half-century-long dominance of the single lens reflex design in interchangeable lens cameras.

Whilst the G1 was praised for its feature set, handling and overall responsiveness, the lack of video recording capability seemed odd at a time when movie modes were starting to appear on conventional SLRs. The irony that conventional SLR designers wanting to add a movie mode have considerably bigger hurdles to jump than Panasonic with the all-digital, mirrorless G1 was compounded by the arrival of the GH1 and GF1 models a little later - both sporting movie modes.

But that was then, and this is now, and in March Panasonic announced not one, but two successor models (both with movie mode) to the G1, splitting the line into a budget version (the G10, to be reviewed later) and the model featured here, the G2. The thinking behind the decision is simple - cutting back on the expensive stuff like a super-high resolution viewfinder allows Panasonic to compete with the cut-price DLSRs that dominate the big box retailers' shelves. The G10 adds little to the G1 beyond a (MJPEG) movie mode, but loses several of the G1's defining features (big, high res EVF, swivel screen), so for us the G2 is by far the more interesting model. In both cases the physical design and the sensor inside are essentially unchanged in this upgrade.

The G2 is an evolutionary - but nonetheless solid - upgrade to the G1, that answers some of the criticisms of the original model, adding the aforementioned video mode (720p AVCHD lite or MJPEG) and tidying up and expanding the external controls. The other big news is that the G2 gets touch screen technology (seen on several Panasonic compact DSCs) - not exactly high on our list of ways in which the G1 could be improved, but in the era of the iPhone something that undoubtedly looks good on the marketing materials, if nothing else.

Touch screen cameras aren't a particularly new idea (it could be argued that they started appearing before the touch-sensitive technology or user interfaces were really ready), but this is the first interchangeable lens camera we've seen to add the feature. Crucially, the G2's touch-screen options are in addition to, rather than a replacement for, traditional controls.

Key features at a glance

• 12.1 million (effective) pixel 4/3 LiveMOS sensor
• Venus Engine HD II with intelligent auto and Intelligent Resolution
• Movie capture (720p) in AVCHD Lite or M-JPEG formats
• 3.0" multi-angle 460,000 dot touchscreen display
• 1.4 million dot Color Electronic Viewfinder
• External mic connection

The G2 features a touch-sensitive screen that can be used to select focus point, adjust camera settings and even fire the shutter. However, no conventional controls have been removed, so it can still be operated almost exactly like a G1. An oddly-shaped stylus is provided but we found the pressure-sensitive screen responsive enough to not need it. The G2 uses the eye sensor to the right of the electronic viewfinder (inherited from the G1), to detect when your face is close to the viewfinder and disables the touchscreen, to prevent unintended nose operation.

A new kit lens

Along with the G2 and G10, Panasonic has announced a new kit lens - a lighter, larger, less rangy 14-42mm F3.5-5.6. It loses its O.I.S image stabilization switch, passing control to the camera body. Despite the lens body being 5mm longer, a plastic mount and other materials changes have helped the 14-42mm shed 30g compared to the 14-45mm's 192g.
The optical design has changed, but the basic specification of 12 elements (1 of them aspherical), in 9 groups is retained. Panasonic says the performance should be to the same standard as its predecessor; we'll look at this later in the review.

Compared to the G1 For the most part this is a case of 'evolution, not revolution' when compared to the G1, but some subtle changes have been made to the body in its latest incarnation At first glance there is little distinction between the G1 (left) and G2 (right) beyond the video-related decals. On closer examination you'll notice that the control dial has been moved to the rear of the camera and the hand grip very slightly re-shaped. The area around the lens mount is also slightly more substantial and features two extra screws below the lens. As well as the repositioned dial, an extra button has been added above the four-way controller. The touch screen is noticeably less reflective than the G1's LCD. Most of the changes are fairly minor attempts to refine and improve the G1's already very good control and handling but there have been a handful of hardware changes made too. The remote control socket now doubles as a stereo mic input, though sadly it remains a 2.5mm connector, rather than the more common 3.5mm style. The G2 loses the card door that appeared on the G1's right flank. Cards, including the large capacity SDXC type, now live alongside the battery (which is bad news for tripod users). The controls on the top left of the camera become more sophisticated, adding focus point selection mode to the corner dial and transferring focus drive mode to a new switch that encircles the base of it. The controls at the top right have also been juggled around - iA mode leaps off the dial to its own button, next to the new direct movie record button. The Q.Menu and Film Mode functions are moved to buttons on the back of the camera. On the button-front there's been something of a reshuffle - all the key players are still around but now hold slightly different positions. The big gains are for AF-point selection mode, which gets added to the G2's scaled-down retro-styled combination dial and switch, and the newly arrived movie mode, which has a direct start button. Intelligent Auto mode also gets its own button, having been displaced from the mode dial by Movie P mode. Q.Menu, exiled from the top plate, finds a new home on an additional button on the camera's rear (just next to where the 'Q.Menu' virtual button appears on the touch screen). Film Mode, which also used to occupy the top of the camera gets shunted to the four-way controller, nudging AF-point selection down to the Fn button. As a result, the only function to lose direct access is metering mode, which instead becomes one of the other options available for the Fn button (there's a choice of ten, rather than the G1's five). Panasonic DMC G2 compared to G1 and G10 G2 changes over G1 at a glance Movie mode + Audio recording (built-in mono mic, connector for external stereo mic) Venus Engine HD II processor (with 'Intelligent Resolution') Control dial moved from front to back Touch Screen 1:1 aspect ratio option Expanded ISO range (now goes up to ISO 6400) iA and movie buttons added Focus mode (AF point selection) dial Minor button / dial function changes SD card now in base with battery Live View can be maintained during continuous shooting (at Medium and Low burst rates) Improved Auto ISO algorithm (maintains higher shutter speeds) Autofocuses with most Four Thirds SLR lenses Basic distance scale added for manual focus The DMC G2 is at first glance a fairly gentle update of the G1, once you've got to grips with the touch-screen. Beyond that, the most obvious differences are the refined ergonomics and the addition of AVCHD video recording. There are also a few minor tweaks to the available options, such as the addition of a 1:1 aspect-ratio shooting mode and ISO 6400. Delve a little deeper, though, and you'll find a few other welcome fixes to some of the G1's less obvious shortcomings. Perhaps most importantly, the G2 (and G10) can maintain live view during continuous shooting if you're willing to drop the frame rate from the 'H' setting (3.2 fps) to 'M' or 'L' (2.6 and 2 fps respectively), which makes a huge difference when trying to follow moving subjects. The Auto ISO algorithm has been tweaked to maintain higher shutter speeds - for example with the 20mm F1.7 it starts to raise the ISO at 1/60 sec rather than 1/30sec. This may not sound like much, but it reduces the risk of getting blurred shots either from camera shake or subject motion, making Auto ISO much more useable in practice. On the focusing front, both cameras gain the ability to autofocus with almost all Four Thirds SLR lenses, and while AF is (of course) still distinctly slow and hesitant, this makes them more appealing to anyone with a collection of Olympus ZD lenses. For manual focusing, a basic distance scale can now be displayed, and while this is nothing more than a line marked with the current focus position in relation to infinity and closest focus, it gives solid feedback about what is happening when you turn the focus ring (which really comes into its own when using lenses like the 45mm F2.8 Macro with magnified focus assist enabled). DMC-G10 differences The G10 is, in many respects, even more similar to the G1. It doesn't offer the G2's touch screen, direct movie button or the combined dial/switch on the top left corner of the camera. Its button layout is closer to that of the G1's, too - the Q.Menu button has moved to the back of the camera and the iAuto button has replaced Film Mode but everything else remains the same with AF point selection holding its position on the four-way controller. The G10 still offers 720p movies from the mode dial though not in the more efficient AVCHD format and loses all movie-related branding from its front. It also gets a smaller, lower-spec viewfinder that's similar to the GF1's add-on unit (202K dots, rather than 1.4M) and loses the articulated tilt/swivel LCD. Unlike the G2, it is only available in black and offers no external mic input.

The control dial has moved to the back, GF1-style (so is now thumb-operated), which is an improvement over the too-easily-knocked position on the G1, and a lot better suited to such a small body. There's also a few button/switch changes, but physically the G2 is otherwise very similar to its predecessor. From a design point of view the G2 is, in almost every respect, very careful to mimic DSLR design, with a large grip, large viewfinder and a bunch of buttons and dials pretty much where you'd expect them to be. And the result is a camera that will be instantly familiar to users familiar with DSLRs and, perhaps more importantly, one that is consistent with the expectations of users aspiring to own a DSLR. The soft micro-textured finish and overall build quality appear to be pretty much the same as the G1, and give the G2 a reassuringly solid, quality feel that seems to be capable of taking the kind of everyday knocks it might receive in normal usage (after a few weeks of heavy use we saw no signs of damage to the surface). In your hand We've been using the G1 and GH1 regularly for over a year now and have really come to appreciate the superb handling, which is as good as any entry-level DLSR (and most mid-range ones too). Moving the control dial to the back is a big improvement, leaving the index finger to rest on the shutter release and the thumb to effortlessly change settings. Our only complaint is that - until you've been using it for a while - the iA and movie buttons are a little too easy to mix up. Viewfinder The G2 has exactly the same viewfinder as the G1 and GH1 (click here to read more about it), which is no bad thing, since it's really rather good. There's still the slight color 'tearing' if you move your eye too quickly, but the sharpness, resolution, refresh rate, brightness and color are excellent. The G2's viewfinder is noticeably larger than most SLR finders and is perfectly usable in all but the lowest light (when the display gets a little noisy and a little laggy). Viewfinder view In keeping with the G2's aim of behaving exactly like a DSLR, the EVF very closely mimics the appearance of a DSLR. And, unlike DSLRs with Live view, the layout of the information is consistent between the viewfinder and the rear LCD (unless you're using the Status Panel mode on the rear screen). The result is no hunting around for settings - they're always shown in the same place. And, unlike a DSLR, the G2's viewfinder can show you the options for each setting and update the preview image to reflect any changes made. The only differences between the G2 and its predecessor are the video mode and Intelligent Resolution icons. Body elements Although it takes the same (1250mAh, 7.2V) battery, the G2's battery compartment is now also home to the SD card slot (which used to be accessed from the side of the camera). This is bad news for tripod shooters who regularly need to change cards (including, it should be said, dpreview camera reviewers), but won't affect anyone else. The new model is compatible with the latest SDXC card format. Like the G1, the G2 has a 3.0" wide screen display built onto a hinge that allows it to swivel and tilt. The LCD is made up of 460,000 dots, making it one of the higher-resolution examples available. While in resolution terms it's not quite on a par with the VGA screens that have almost become standard on DSLRs its 60fps refresh rate produces a much smoother live view image than on most DSLRs. The screen can be turned around completely ('face in') to protect it when not in use. The big change is that the screen is now touch sensitive. You can control most menus, set the focus point or even take pictures directly by touching the screen if you so fancy. We'll look at the touch screen interface in more depth later. The important point for us is that it isn't designed to replace any other form of control, so in no way compromises handling as it so often does on compacts. The G2's rather small flash has a Guide Number of just 11, slightly on the low side for a camera in this class, but plenty for the occasional social snap in low light or for a bit of fill-in on a sunny day. The G1's tiny kit lens means that, even though the flash doesn't pop up very far, there's little risk of it casting shadows into your photos unless you use the lens hood at the same time. You can, of course, increase flash power by attaching a dedicated unit to the built-in hot shoe. The G2 has a metal tripod mount, which should reduce concerns about stripping its thread. It's perfectly lined up with the lens but the camera is so small that you can give up on the idea of changing batteries or cards with most tripod plates attached. On the left hand side of the camera is a combined USB/video out connector and a HDMI port for connection to your HDTV. No HDMI cable is included with the camera, however, so that's something you may need to invest it. Above the main ports there's a combined external microphone / wired remote control socket. In one of the only significant changes to the body, the main control dial has migrated from the front grip to the back of the camera (where it is operated by the thumb, rather than the forefinger). It may seem like a minor change, but on small cameras it's often the placing of buttons and dials that makes the difference between usable and unusable manual controls. The good news is that the new dial position is, according to everyone here, a big improvement. The top plate has had a bit of a re-jig too - gone are the Q.Menu (moved to the back of the camera) and the pointless dedicated 'Film Mode' button, replaced by a direct movie button and an illuminated iA (Intelligent Auto) button (which overrides any current settings to return to full auto mode, lighting up bright blue in the process). The left-hand dial is still dedicated to focus functions, but now has an extra lever around its base meaning it now covers focus area (single, multi, tracking, face detection) and focus mode (single or continuous AF, manual focus). Operation and controls Putting aside the new touch screen controls for a moment, the physical controls and overall operation of the G2 are very similar to the G1 and GH1. This is no bad thing, as those cameras (and this one) offer excellent handling that isn't harmed at all by the slightly smaller form factor (unlike the GF1 and Olympus Pen models, which arguably sacrifice handling for size). The extensive external controls are complemented by an easy to master on-screen interface that might not look great, but does a decent job of providing logical access to the comprehensive feature set. The on-body controls have moved around a little but are similar enough that anyone upgrading from a G1 will soon feel at home. Unlike many entry-level DSLRs the G2's compact body is covered in buttons and dials that offer a surprisingly traditional approach to picture-taking. But don't worry too much about messing things up by playing with the many functions: the excellent iA (Intelligent Auto) mode is always just a click away, thanks to the prominent new button near the main mode dial. A summary of the physical control changes over the last generation is listed below: Film Mode moved from top plate to left arrow key Focus pattern moved from 4-way controller to new lever on top plate Q. Menu button moved from top plate to rear Focus area selector moved to top dial (left side) iA mode moved from mode dial to button on top plate New Movie button on top plate Rear of camera controls The G2's crowded rear panel is similar to the G1/GH1, with one extra button (Q.Menu, moved from the top panel) and the newly positioned 'click & turn' control dial (used to change exposure settings and navigate menus). Top left is the EVF/LCD button to toggle between framing with the viewfinder and the LCD screen (only really used if you turn off the eye-detecting auto switch function). To the right of the viewfinder we have the AE/AF lock and play mode buttons, and the control dial. Below the thumb grips sit the Q.MENU and DISPLAY (for changing the amount and type of information overlaid on the live view and playback displays) buttons. Below this is the ubiquitous four-way controller. Each of the directional keys has a dedicated function in record mode, giving direct access to ISO speed, film mode and white balance, plus a customizable function button (Fn). Bottom right of the back is the depth-of-field preview button (which doubles up as a Delete button in playback mode). In most cases the functionality of the external buttons is replicated in the quick menu (invoked by pressing the Q.Menu button or touching the icon on the touchscreen). Top of camera controls Anyone who hates menu-driven control systems will love the G2. Like its predecessor the top plate is densely-packed with knobs and dials that further enhance the 'traditional camera' impression created by the styling of the body itself. The big changes here are the inclusion of a movie clip button (for capturing quick movies when in one of the stills photography modes) and an illuminated iA button that instantly overrides any manual settings and puts the camera into its (remarkably reliable) 'idiot proof' Intelligent Auto mode. On the left shoulder the focus mode dial from the G1 now doubles as a focus area selector. The main mode dial has lost its iA mode position (replaced by the Motion Picture mode) but is otherwise identical to the G1. The G2 offers a wide range of shooting modes from the fully manual to the fully automatic. Program Auto (with Shift) Aperture Priority Auto Shutter Priority Auto Manual Custom (3 memories) Movie-P SCN (Sunset, Party, Baby 1, Baby 2, Pet, Peripheral Defocus) Night portrait (with four options) Close up (4 options) Sports (4 options) Scenery (4 options) Portrait (5 options) MyColor mode (custom control over color, saturation and contrast) On-screen controls and menus Aside from the new touch screen features, the G2's interface and menu system is very similar to the G1, GF1 and GH1. The menus have been jigged around a little, but for anyone already using a Panasonic moving between the G2 and any of its predecessors will be an almost entirely seamless process. Those who haven't will probably find the sheer wealth of options (and the fact there are often several ways to do the same thing) a little overwhelming at first, but if you like a lot of control at your fingertips (with a decent amount of customizability thrown in for good measure), the G2 won't disappoint. For a more in-depth look at the various record mode functions (including the clever shutter speed preview feature) check out the displays section of the Panasonic G1 review. Record mode display options The G2 offers three display options in record mode. The first shows only the most basic shooting information (mode, exposure settings, AE compensation, flash mode) - and then only when you half-press the shutter. The second shows full shooting information along the top and bottom edge of the frame. Most of the icons correspond to functions accessible via the Quick Menu (see below). The third option is a status panel. Press the Q.Menu button and use the front dial (or arrow keys) to select the setting you want to change. Press the dial to change the setting. It's a fast and efficient way to use the camera. Note that the EVF continues to show the live view when you're using the Status Panel display mode on the main screen, so you can use the camera much as you would a conventional SLR. This screen can also be controlled by touch (see below). As in previous G cameras you can choose between two different display styles for the electronic viewfinder and screen independently. The second option, 'Finder Mode' adds a black border, making the information at the bottom a little easier to see. The display in the viewfinder in this mode is a little different, being designed to mimic a conventional SLR. The icons are all green (unless selected). Note that the screen is 3:2 and the viewfinder is 4:3, and you won't seen the black bar across the top in the viewfinder when the image is shot in 4:3 mode (or in 4:3 or 3:2 on the rear screen). Quick Menu The G2 has the same Quick Menu you'll find on all Panasonic G cameras (and many of its compacts). It allows you to cycle through the various on-screen icons and change their settings directly. The menus displayed are slightly different depending on the display mode chosen, and if you're using the touch screen, but the mode of operation is always the same. You can read more about the Quick Menu (and all other aspects of control and operation) in the G1, GH1 and GF1 reviews. Direct access buttons Buttons such as white balance and ISO display a dedicated mini menu on the LCD monitor/EVF which allow you to see all the options available, at which point you use the command dial or arrow keys to change the setting. New in the G2 is the ability to simply touch the screen to change settings once you've brought up the menu with the button on the body. Setting ISO after pressing the ISO button. Note that you can use the touch screen or the more conventional arrows/dial method to select the setting required. Changing film mode also allows you to quickly adjust image parameters (contrast, sharpness, saturation, noise reduction). Touch screen The biggest new feature of the G2 is undoubtedly its touch-sensitive screen. The underlying screen is still the same high-resolution 460,000 dot LCD on a tilt and swivel mount that appeared in the G1 but it now has a pressure-sensitive layer added. As mentioned earlier in this preview, all the original hard-button functionality of the G1 is still there and can be used without the touch-screen interfering. Everything the touch-screen brings is an addition and many of them prove to be rather welcome additions, based on our everyday use during this review. Users of manual focus lenses are likely to appreciate the ability to just press the area of the screen they want magnified, for instance. Overall, though, we didn't find ourselves using the touchscreen anywhere near as much as we had expected. This is partly down to personal preference (after decades doing it 'the old way' a touchscreen on a camera like this just doesn't feel right), but mostly because the G2 has such excellent physical controls that it's almost completely superfluous. We found that accessing menus (such as the Q.Menu) was a little hit and miss (the screen is too small and the icons too close together), but the ability to pick a focus point just by pointing (especially with moving subjects, on a tripod or when shooting movies) is a very useful feature. Ultimately, the touch screen provides some cool tricks and is certainly fun to play with, but literally the only thing we ever used it for was AF point selection (when shooting a fast-moving toddler or when working on a tripod). It adds little - or nothing - to the handling or ergonomics in most shooting situations (in fact we found trying to use it often got in the way of actually taking pictures), but the ability to effectively point to something on the screen and have the camera focus on it and take a picture (or track it as it moves around the screen) is incredibly useful. And of course a lot of this is personal opinion - if you've never used an SLR but are a big user of a touch screen phone then I'm sure you'll feel right at home with the the G2 (it's not iPhone responsive, but it's a lot better than most we've tried). There doesn't appear to be much of a premium charged for it, and it doesn't replace any of the existing controls, so on balance, has to be considered a good thing. Touch the screen anywhere to focus. Sliding your finger up or down the scale that then appears on the right changes the size of the focus area. The same actions can be performed via the four-way controller and control dial if you prefer. Two icons that usually appear on the right of the screen give access to a touch-sensitive version of the Q.Menu or engage touch-shutter mode that focuses and takes a picture when you press the screen. Both options can be switched off if you prefer. The touch-sensitive Q.Menu allows you to press any of the icons along the top or bottom of the screen. Touch-sensitive regions are clearly marked out in dark gray. A description of the selected setting appears for just over three seconds, obscuring half the icons. The options include a well-implemented exposure compensation scale, though it's rather easier to make large adjustments than it is to make the 0.3EV corrections you're most likely to make. (The control wheel can still be used, though). Another display option is the interactive display panel as seen in other G series cameras. Only on the G2, pressing on any of the options allows you to change it. Each option gets its own screen with options arranged on a plain background, except for White Balance, which appears over the preview so you can see its effect. The exposure 'dial' doesn't work so well. You have to press on the center to activate it (even if exp. comp. is already selected via the control dial), then slide your finger around the circle to change the amount. However, the design is directly adapted from older G series cameras, where it wasn't a problem that touching the edge of the circle means your finger completely obscures the display of how much exposure comp you've applied. In playback mode you can scroll through the images by swiping your finger across the screen (right-to-left to see the previous image, which seems like the wrong way round, somehow). Alternatively, pressing the screen in a single place zooms into the image, allowing you to roam around the image by moving your finger. Record review & play displays The G2 provides four different display modes in playback, press the DISPLAY button to cycle through them. You can have blinking highlights (this in an option you have to turn on in the setup menu) and RGB histograms and the usual array of shooting information. 1. Full screen image with no information 2. Full screen image with information overlaid. Press the down arrow to mark an image as a 'Favorite'. 3: Small image, full shooting information 4. Small image, basic shooting information and R,G,B and Luminance histograms Playback zoom (up to 16x) can be activated by turning the control dial to the right or simply by touching the screen (you can also scroll around the magnified image by simply sliding your finger across the screen). Turning the dial to the left allows you to choose from 12 (4x3) or 30 (6x4) thumbnails or use a calendar view to find images shot on a specific date. Overall handling and operation With one very obvious difference, the handling of the G2 is very similar to the G1 and GH1, and we would encourage you to check out those reviews here and here if you haven't already. The difference, of course is the touchscreen, which we investigated in detail in the 'operation and controls' section of this review. Putting the touchscreen aside for a moment, the G2's overall handling experience is excellent. Although unashamedly a DSLR-inspired design, in our opinion the G2 is a much more pleasant camera to use than similarly styled 'bridge' designs like Panasonic's own DMC-FZ35. Its speed is a major factor, but also the EVF matches midrange DSLRs for size and brightness, and the refresh rate is high enough that, after a short period of time, it is easy to forget that it is an electronic rather than optical finder. Like the G1 and GH1, the G2 does live view 'right'. In the majority of DSLRs, live view still appears a little bit bolted-on, with relatively limited functionality (e.g. autofocus) and no clear idea of its purpose. Even the more integrated systems have come at the expense of traditional DSLR capabilities, such as the viewfinder. By contrast, the G2 behaves exactly like a DSLR despite being built around live view. Specific handling issues The G2's headline feature is of course its touch-sensitive LCD screen. In general, we're equivocal on touchscreen technology in cameras, because there are all too many examples out there of poorly integrated screens with too little thought given to how people will actually use them. Too many of the touchscreens that we've seen on digital cameras appear to have been added to enhance their marketability, but not their functionality. As we've discussed earlier in this review, in our opinion the G2's touchscreen is great for focus point selection but is otherwise largely superfluous in normal use (of course you have the option of completely ignoring it if you'd prefer to get to grips with physical buttons instead). We hope that Panasonic continues to develop touchscreen technology in future G-series models, but we'd be surprised if we see another implementation as conservative as this one. Performance The G2 is a fast and responsive camera, and in this respect it is exactly what we've come to expect from Panasonic's G-series mirrorless interchangeable lens models. The G1 was the first camera of this type that we tested, and it represented an impressive debut, but the G2 is a worthy successor. Although not notably quicker than its predecessors, the addition of a touchscreen to the G2 changes the ergonomics enough that in some situations (especially when manipulating the single and multipoint AF systems) the G2 is a faster camera to use than the G1 and GF1. Overall performance Considering that the G2 operates, in essence, like a compact digital camera, it is impressively fast in general use, and feels very snappy compared to some of its mirrorless competitors. Startup time is all but instantaneous, and from being switched off to capturing an image (including AF acquisition) takes a mere 2 seconds (approx). In single frame advance shooting, shot to shot time is less than a second. Shutter lag is unnoticeable at 0.1 seconds (approx), image review is all but instant after a picture is taken, and zooming into a captured image using the rear control dial is fast and easy. Things are rather more laggy when the touchscreen is used to zoom into captured images, but even then, we don't feel like the G2 is keeping us waiting. In our review of the original G-series model, the G1, last year, we wrote that we'd used DSLRs that didn't feel as quick as the G1, and that holds true in the latest model as well. Everything, from initiating focus to reviewing a captured image, just feels fast. Continuous Shooting and buffering The G2 can manage a maximum frame rate of 3.3 fps in continuous shooting mode, matching the GH1 and fractionally faster than the G1. In raw mode, the G2 sustains approximately the same 3.3 fps maximum frame rate, but can only manage 5 images in a sequence before slowing to allow the buffer to clear. In JPEG mode, burst depths decrease slightly when slower SD cards are used. Unlike many DSLRs (and some compacts), the G2 does not give any indication of the amount of buffer available during continuous shooting, instead once the buffer is full (using a fast card this pretty much only occurs when shooting RAW) the camera simply slows down its continuous rate. A gauge or 'water tank' type display indicating how much buffer space is available would be useful. The following figures are taken from performance with a Sandisk Extreme III SD card, at ISO 100, in manual mode (iExposure and NR turned off). JPEG (Fine): around 3.3 fps for 42 frames RAW: around 3.3 fps for 5 frames, then around 0.6 fps RAW + JPEG: around 2.5 fps for 4 frames, then about 0.4 fps Recovery time: around 4-6 seconds Where the G2 adds a trick over its predecessors, though, is in maintaining live view at slightly slower burst rates. This works when the burst rate is set to M or L in menu; we found these options to match Panasonic's specified 2.6 fps and 2 fps rates almost exactly. Autofocus speed / accuracy One of the reasons that the G2 feels so snappy is that its AF speed is very impressive indeed. In normal use, the G2's AF feels almost as responsive as a typical midrange DSLR with a kit lens attached. In most shooting conditions, AF acquisition is very speedy, and almost infallibly accurate. Like all contrast-detection AF systems we've used, the G2 does display a momentary 'hunting' when AF is first initiated, but with the 20mm f1.7 pancake lens fitted it takes a mere 0.5 seconds (approx) to alter focus from its nearest focusing distance to a distant object, close to infinity. With the new 14-42mm kit lens, AF is even faster, with the result that to any practical extent, the G2 offers equal or superior AF speed with static subjects to most entry-level DSLRs. One of the things that differentiates the G2 from its DSLR cousins, of course, is that it can offer full-speed face-detection AF. Whereas in a DSLR, face detection (if it is available at all) must be used in Live View mode, with (typically) slow AF, in the G2, it is just another AF mode, as fast as the rest. Face detection is quick to acquire faces, and as we'd expect from a contrast detection AF system, focusing is highly accurate, too. The G2's touchscreen can be used to move the AF point/s around the screen. This takes a little getting used to, but greatly increases the versatility of the system in some situations. In single-point AF mode it is also possible to increase and decrease the size of the AF point, using an on screen slider. This is one area (one of the few, in fact) where using the G2's touch-sensitive screen is truly intuitive. In continuous AF mode, the G2 obviously can't match the likes of the Nikon D300s or Canon EOS 7D for accuracy, but for a contrast-detection AF system, it's about as good as it gets on the market at the moment, and certainly superior to competitors like the Olympus EP-2 and Sony NEX-5, which feel twitchy by comparison.     Camera Menus The G2 fits its many options onto 20 pages of menus. These are divided into six categories: Record, Motion Picture, Custom Menu, Setup, My Menu and Playback. Although they've been jigged around a bit since the G1, generally you'll find all the options where you'd expect them and, after a short while with the G2, navigating the menus is easy. Note that you get a much smaller subset of menus in full Auto mode. Record menu The record menu is very similar indeed to the G1/GH1 (the only significant change being the option to turn on the new Intelligent Resolution feature). In this table and all those that follow the * indicates a material change over the last generation (we haven't marked all the menu items that have moved).
