Olympus XZ-1 Brief Hands-on Preview

January 2011 | Richard Butler

preview based on a pre-production XZ-1
Back in 2001, when it was possible to charge $999 for a compact camera, Olympus produced the C-3040Z, C-4040Z and C5050Z which featured some of the brightest zooms to ever appear on such cameras. Sadly, as the years have gone on and prices have dropped, Olympus moved away from this part of the market and it's been a long time since we looked to it for class-leading compacts.
Despite the falling price of entry-level DSLRs and the arrival of their more compact mirrorless competitors, the enthusiast compact sector has seen a resurgence, with Samsung and Nikon weighing-in and Canon going as far as bringing a second model to the melee (the S90 revived the PowerShot 'S' series to sit alongside the company's stalwart G series). Olympus, meanwhile, has remained quiet.
Today it becomes apparent that it hasn't been sitting idly by - instead it has clearly been watching the sector very closely and has studied the available cameras keenly. The result is the XZ-1: an enthusiast compact that takes the best elements of its rivals and synthesizes them into a very attractive package.
There's a bright lens, of course, with the XZ-1 becoming the first of the company's compacts to ever wear its respected 'Zuiko' designation. And it's clear why the company would want to draw attention to the optics, having created the brightest zoom lens of any current compact while still offering a truly useful range. The i.Zuiko lens is F1.8 at the 28mm equivalent end and a still very impressive F2.5 at the 112mm setting.
But the spec doesn't end at the lens - the XZ-1 is built around a high sensitivity 1/1.63" CCD which, along with its peers, makes it one of the larger sensors to appear in a compact camera with a built-in lens. To this it adds two control dials (including an S90-style dial around the lens) and a bright, high-resolution OLED screen. Other high-end highlights include a flash hot shoe and the ability to wirelessly control off-board flashguns. It's hard to imagine what else Olympus could have fitted into the XZ-1 attractive metal-fronted body.
From the front it's clear that the XZ-1 is slightly larger than the two smallest enthusiast compacts (the Panasonic LX5 and Canon S95). It's about the same size as Samsung's EX1/TL 500, making it much more conveniently sized than the larger Canon G12 or Nikon P7000.
The top-down view emphasizes the dimensional differences between the three cameras and also shows the flash hot shoe.
Olympus XZ-1 specification highlights:
  • High Sensitivity 10MP CCD sensor
  • 28-112mm equivalent lens
  • F1.8-2.5 maximum aperture
  • CCD-shift image stabilization
  • Twin control dials, including one around the lens
  • ISO 100-6400
  • New TruPic V processor (as used in the company's PEN series)
  • Large 3.0" 621k (VGA equivalent) OLED display
  • 720p movie mode (30 fps in Motion JPEG format)
  • Micro HDMI connector
  • 6 Art Filters (As per the PEN series)
  • In-camera RAW conversion
  • Built-in flash, hotshoe and remote flash control
  • Built-in ND filter

In the hand

Despite its lack of grip, the XZ-1 fits well in the hand. The front dial encourages a stable, two-handed grip (not pictured), and when holding the camera in this way the controls are easily accessible and (we think) well-positioned.

Key features / what's new

It's hard not to view the XZ-1 as a synthesis of the best elements of its peers, with its S95-style lens control dial, 1/1.63" high-sensitivity CCD sensor, fast lens and manual controls. In terms of specifications it is the class front-runner in almost every respect, and achieves this trick without being as bulky as cameras like the Canon G12 and Nikon P7000.
The 1/1.63" sensor sounds like it should be slightly larger than the one that appears in the rest of its peer group (The Canons, Samsung and Nikon appear to share very similar 1/1.7" sensors). However, the other 1/1.63" sensor we know is in the Panasonic LX5, which doesn't ever use the full area of its chip (instead it uses different regions of the sensor to offer a range of aspect ratios with the same angle-of-view). Our suspicion is that the Olympus is using a similar chip. If this is the case, then unlike the Panasonic, it doesn't use areas of the sensor outside the 4:3 crop, meaning the area of the chip being used isn't significantly larger than the cameras it competes against.
The headline feature of the XZ-1 is undoubtedly its 'i.Zuiko' lens. Even in a category of cameras with bright lenses, it stands out. It offers a currently unbeaten combination of range (28-112mm equivalent) and brightness (F1.8-2.5). Its maximum aperture stays better than F2.2 until around 100mm equivalent, making it brighter than the previously class-leading Samsung EX1/TL500 (which is F2.4 at its 72mm limit).
The XZ-1 features a 610k dot OLED display. The specification is identical to that of the unit used in Samsung's TL500/EX1 enthusiast camera. Close examination of the panel shows it appears to be using the Samsung-owned PenTile pixel arrangement. It's a screen that offers superb brightness and contrast with better viewing angles and better battery life than LCD displays are capable of.

In-use

Our first impressions of the XZ-1 are very positive - the twin control dials make changing settings very simple and several key functions (AF area, flash control and drive mode) are available on the four-way controller. Other functions are also fairly easily accessed - pressing the INFO button brings up a variation of the 'live control screen' function menu seen on the PEN series. We're disappointed not to have direct access to the ISO setting in Aperture Priority and Shutter Speed Priority modes but the live control screen does at least remember the last-used setting, so will revert to ISO if you're regularly changing it.
The XZ-1 also gains the simplified 'live guide' interface in the beginners' iAuto mode. This introduces a series of results-orientated sliders to allow control over depth-of-field, white balance, saturation and so forth, without having to learn about F-numbers and color temperature. It's a system that makes it easy to adjust an aspect of your photo if you're just trying to point-and-shoot (you can only change one parameter at a time). We'd like it to give some hint about what it's changing, to help make taking control seem less intimidating to beginners, but it should still encourage a greater degree of creativity, which can only be a good thing.
Meanwhile, the XZ-1 improves on the PENs to an extent with a very simple menu system. It means the camera doesn't have nearly the (occasionally excessive) level of customization of those cameras but also means that, on the rare occasions you have to visit the main menu system, you can quickly and easily locate the feature you're looking for.
The XZ-1 offers two control dials - one around the lens and another on the rear of the camera. The functions of these two rings depends on shooting mode and cannot be customized.

Program ISO Exp. Comp.
Aperture Priority F number Exp. Comp.
Shutter Priority Shutter speed Exp. Comp.
Manual Exposure F number Shutter speed
Custom Defined by shooting mode 'C' is based on
SCN Select scene type Exp. Comp.
Low Light ISO Exp. Comp.
ART Art Filter Exp. Comp.
The XZ-1 features the AP-1 accessory port that previously appeared on the PEN EP-2 and E-PL1, meaning it can be used to connect the excellent VF-2 external viewfinder, SEMA-1 external microphone or MAL-1 LED macro lights announced today.

The port is not the same as that on the E-PL2 however (that camera uses an AP-2 port), so it's not possible to use the newly-announced PENPal Bluetooth add-on.
The small, modestly powered built-in flash pulls off a neat trick - the ability to remotely control and fire compatible flashguns. It's a unique ability in this class of camera and makes the addition of an FL-36R flashgun worth considering.

Also unusually for a camera in this class, the built-in flash can also be set to first or second curtain sync.
The XZ-1 features a fairly small lithium ion battery (LI-50B) with a capacity of 3.4Wh. According to CIPA testing methods this will provide around 320 shots on each charge. This is behind the Panasonic LX5's 400 shots but considerably ahead of the Canon S95's 200.
