Fujifilm X10 Hands-on Preview


The revival of the enthusiast camera sector over the past few years has been a surprising but welcome development in the industry. The widespread acclaim for the Panasonic LX3 has encouraged other manufacturers to join or re-enter the fray with high-end offerings of their own, resulting in excellent, high-spec cameras such as the Samsung TL500, Olympus XZ-1 and Canon S95.
Now it's time for Fujifilm to play its hand, which it has done with its X10. Conceptually it borrows our favorite features from the two distinct sub-types that have emerged in this category - it takes the fast lens from cameras such as the TL500 and XZ-1 and combines it with the optical viewfinder and extensive controls of the Canon G12 and Nikon P7100. Just to finish things off, Fujifilm wraps the whole thing in magnesium alloy bodywork that evokes its big brother, the X100 and the 1960's rangefinders it borrowed its styling from.
The X10's innards are as progressive as its exterior is staid. It features a 12MP, '2/3" type' sensor, which means it's between 26% and 40% larger than the sensors used by its enthusiast compact peers and twice as large as those used in almost all regular compacts. It also uses the company's unique 'EXR' technology that makes it easy to combine pairs of pixels to produce 6MP images that have either been averaged to reduce noise or differently exposed so that more highlight information is captured. The underlying chip uses conventional CMOS arrangement, rather than the back-side illuminated type that can help improve light capture in small sensors.
Bright manual zoom lens
Despite the larger sensor, Fujifilm manages to find room for an image-stabilized, retracting 28-112mm equivalent F2.0-2.8 lens. The wide aperture, combined with large sensor means not only does the X10 offer more control over depth-of-field than any other camera in its class, it also allows for shallower depth of field than most DSLRs when used with their kit zooms, when each are set to their respective telephoto ends.
The lens is manually zoomed, more like those on interchangeable lens cameras and this movement is mechanically linked to an optical viewfinder, meaning you drive the viewfinder as you extend the lens. The mechanically-driven lens and viewfinder design has two key advantages. The first is that it gives a pleasantly direct feeling of control over the lens' behavior, allowing continuous (rather than stepped) zooming. Crucially it also means the camera isn't dependent on its battery for driving the lens and viewfinder. The X10's rather small battery is rated at 270 shots per charge - which would be considerably lower if it also had more motors to drive.
The fast readout from the CMOS sensor allows the camera to shoot at up to 7 frames-per-second at full resolution and 10fps at 6MP. It also enables 1080p30 movie shooting and the creation of panoramas in a single sweep of the camera.
As befits a camera in this class, the X10 can capture Raw images and, in an welcome addition, it can also re-process its own Raw files in-camera (the Olympus XZ-1 is the only other camera in this class we can think of that can do this). Combine this feature with the X10's film simulation modes and color-filtered mono modes and it can be really useful for getting the best of the photos after shooting.

Compared to the Olympus XZ-1
The Fujifilm X10 essentially brings together all the best features of its rivals - a very bright, reasonably lengthy zoom and a high quality glass viewfinder (they're usually plastic in compact cameras). Add to this its larger, EXR sensor and it's amazing the camera isn't much bigger than its peers. Understandably, it is rather more expensive (its launch price was 20% above that of the XZ-1).a
The Olympus XZ-1 has the brightest zoom of any current compact camera, but the larger sensor (and hence longer focal lengths), mean the X10 offers fractionally more control over depth-of-field than the Olympus. Despite this, it's not a much larger camera.
Its bright lens also means that the X10 can give more-blurred backgrounds than a DSLR or large-sensor mirrorless camera with a typical kit zoom (i.e. 18-55mm F3.5-5.6 or 14-42mm F3.5-5.6), which is useful for subject isolation when shooting portraits.a
The X10 is a touch larger than the PEN Mini but it also offers more in the way of direct control. It also contracts to a smaller size than the Mini, despite the Olympus retractable kit zoom and offers greater control over depth-of-field.

Nikon V1 and J1 Hands-on Preview

Nikon's 1 system represents the company's arrival in the mirrorless interchangeable lens camera market. Like its rivals, the company says it is targeting the compact camera user who wants better quality but is put off by the size and complexity of a DSLR. We spoke to the company when the system was first launched and wrote about our first impressions.
According to Nikon, the 1 system has been four years in the making. Tracking back, this means that Nikon started work on its new mirrorless system in mid-2007 - about a year before Panasonic launched the pioneering Micro Four-Thirds system with the Lumix DMC-G1. The result of all this work is two cameras, based around a completely new lens mount and a unique 'CX format' sensor.
At 13.2 x 8.8mm, the 10MP sensor inside these new cameras (common to both models) is small by comparison with most of their mirrorless peers, and results in a 2.7x effective focal length multiplier (which sees a 10mm lens becoming an 'effective' 27mm). Now that the dust has had time to settle, it is fair to say that this decision surprised a lot of people, and disappointed many. It is very clear that, as far as Nikon is concerned, the J1 and V1 belong to a new market segment, distinct from the one targeted by Sony's NEX series or Panasonic and Olympus' Micro Four Thirds models.
From the top, you can see that the J1 is slimmer than the V1, which is actually one of the chunkiest compact form-factor cameras of its type. From this perspective you can also see how much the V1's EVF housing protrudes behind the camera.
The differences between the J1 and V1 are important - the V1 has a built-in 1.4M-dot LCD viewfinder, while the J1 does not. However, despite being the cheaper, simpler model, the J1 has a built-in flash which the V1 lacks. The V1 makes up for this omission with a multi-accessory port that can be used to mount a dedicated external Speedlight SB-N5 flashgun or GPS unit.
The V1 has a higher resolution rear LCD screen and a mechanical shutter, which makes it a better choice for high framerate captures of moving subjects. The mechanical shutter also allows it to use flash at shutter speeds of 1/250th of a second, rather than the 1/60th that the electronic shutter limits the cameras to. Ergonomically though, with the exception of the V1's built-in EVF, both cameras handle in much the same way. Both lack a traditional exposure mode dial, and neither camera offers much in the way of customization. Both are - in essence - designed for multi-purpose point and shoot operation.
The shooting experience

The Nikon V1 is the more enthusiast-oriented of two cameras in Nikon's brand new 1-system. Ahead of a full review, click on the link below to read our first impressions.

Panasonic Lumix DMC-GX1 Hands-on Preview

Panasonic's Lumix DMC-GX1 is the company's latest addition to its G-series lineup. And although the camera bears the '1' appendage in its model name, it is clear from even a cursory glance that with the GX1, Panasonic has provided the long-awaited spiritual successor to the highly regarded Lumix DMC-GF1. Of perhaps even greater significance, the move to introduce a separate GX product line (as opposed to releasing the camera as a 'GF4') would seem to suggest a long-term commitment by the camera maker to meet the demands of enthusiasts who embraced the GF1.
Launched back in 2009, the GF1 was, ironically, Panasonic's attempt to court compact-camera owners looking to upgrade, with what was then billed as, 'the world's smallest, lightest interchangeable lens camera'. Instead, the GF1's high quality Raw output and classic rangefinder aesthetic gained a strong and passionate following in the enthusiast market. DSLR owners looking for a second 'go-anywhere' camera with high image quality embraced the camera's external control points and its relatively compact Micro Four Thirds lens offerings.
It is precisely these users who have been disappointed twice over with the Lumix DMC-GF2 and Lumix DMC-GF3 releases, which broke with the retro styling and button-driven operational control in favor of ever-smaller form factors and design cues that pointed unambiguously to users who may be turned off by an overly complex (and expensive) camera. With the GX1 Panasonic is taking square aim at more advanced users for whom the GF1 struck a pleasing balance between size and operability.
Of course, the competition for these users has grown much stiffer today, and Panasonic recognizes that if it wants to expand the camera's appeal, the GX1 must offer advantages not only to the GF series but to a crowded market that includes strong APS-C sensor competition from both Sony and Samsung. In this regard, the GX1 employs a 16MP sensor that we have been led to believe is identical to the chip recently seen in the Lumix DMC-G3, although it is now being pushed to a top ISO of 12,800.
A brand new viewfinder, the LVF2 has been introduced alongside the GX1. With a higher magnification and resolution, the LVF2 is a noticeable improvement over its predecessor, the LVF1. Crucially though, a new spec and connector makes the LVF2 incompatible with any GF models; neither is it possible to fit the LVF1 on the GX1. Faster communication between the camera and lenses helps the GX1 focus even faster than the 120Hz sensor readout allowed in the recently released G3 and GF3 models, with Panasonic claiming a 10% improvement.
Panasonic's well-regarded touchscreen interface has also gotten some new tricks, with a level gauge and clever Touch Tab icon that allows you to hide, reveal (and of course activate) a small panel of menu options directly on-screen. Another very welcome feature is the inclusion of an orientation sensor that automatically rotates vertical images even when captured with non-OIS lenses.
The GX1 is being made available in both black and silver bodies. Unlike previous GF models, none of the GX1's kit options includes a fixed focal length lens. Instead, the kit lens options are limited to just two; the Lumix G X Vario PZ 14-42mm F3.5-5.6 ASPH Power OIS zoom lens and the more conventional (and less expensive) Lumix G Vario 14-42mm F3.5-5.6 ASPH OIS lens.
By creating a separate product line for the GX, Panasonic has by implication made clear that it sees significant growth potential in its GF lineup among compact-camera upgraders. With the GH2 appealing to users who shoot a lot of video and the G3 designed for (primarily) still shooters who desire a built-in EVF and articulated LCD, the GX1 is rather sensibly positioned as an enthusiast offering for those who want the highest image quality from a Micro Four Thirds camera, in a form factor that comfortably accommodates a range of zoom lenses and does not skimp on external controls.
Panasonic GX1 specification highlights
  • 16MP Micro Four Thirds sensor
    ISO 160-12,800
    Orientation sensor (providing information with non-OIS lenses)
    3.0", 460k dot LCD
    Full AVCHD 1080/60i video (from 30fps sensor output)
    Continuous shooting up to 20fps (at reduced resolution)
    Electronic level gauge
    Four available Fn buttons (two onscreen)
Differences between the GX1 and the GF1
  • Higher resolution sensor (16MP vs 12MP)
    Touchscreen interface
    Top ISO of 12,800 (vs 3200)
    AVCHD 1080/60i video (vs 720p AVCHD Lite format)
    Stereo mic
    Electronic level gauge
    Two additional Fn buttons
    Compared to the Samsung NX200
 The Panasonic DMC-GX1 is taller than the Samsung NX200, which actually houses a larger APS-C sensor. The GX1's mode dial sits atop the camera plate as opposed to the recessed profile found on the NX200.
 From this top view you can see that the GX1 packs more control points along the camera's top plate, which maintains a traditional rangefinder-inspired shape compared to the more aggressively contoured design of the NX200.
