First impressions of the Fuji x10 camera

The Fujifilm x10

Despite limited supply, I managed to get my own Fujifilm x10 Camera a few weeks ago and play with it a bit. The x10 falls into the category of “enthusiast compact camera,” meaning that it has several advanced features that will appeal to serious amateur photographers. Most importantly, the Fuji x10 offers manual (and easily accessible) control of exposure. Shutter speed, aperture, ISO and exposure compensation can all be adjusted with just a few clicks, turns or button presses — rather than a hunt through several layers of menus. White balance adjustment can also be accomplished with a minimum of fuss.

The sensor in the x10 is physically a bit larger than you’d find in most point and shoot cameras, which should translate to lower noise at higher ISO settings. Combining this larger sensor with a wide aperture will also produce shallower depth of field than would be possible on most point and shoot cameras. The lens of the x10 zooms through a range with angle of view (in terms of a 35mm full-frame camera) equivalent to 28mm-112mm. Impressively, it offers a maximum aperture of f2.0 at the wide end of the zoom range, and maintains a maximum aperture of f2.8 even at the telephoto 112mm. Fuji has a reputation for making excellent optics — high-end Hasselblad H2 lenses are made by Fuji. (Yes, I know that many Hasselblad lenses are made by Carl Zeiss or Schneider Kreuznach–but indeed, many lenses for the H1 and H2 are made by Fujifilm, as were some earlier Hasselblad lenses for film camera systems like the panoramic XPan.)

The retro styling of the x10 is reminiscent of Leica rangefinder cameras, including an optical viewfinder located off-center above the lens. Most compacts forgo an optical viewfinder in order to reduce the size of the camera, expecting the photographer to compose with the LCD instead. Using the LCD has some drawbacks, though — it eats up battery power and can be hard to see in bright light. The optical viewfinder on the x10 is not TTL. Consequently you won’t see an accurate representation of depth of field, and at macro range you’ll have a severe parallax problem if you try to use the optical finder. (The finder does zoom with the lens, though.)

The Fujifilm x10 is approximately the same size as an Olympus PEN. Note that the Olympus is wearing a 17mm prime lens (no zoom) , whereas the lens on the Fujifilm zooms from wide to telephoto. The Fujifilm x10 also has an optical viewfinder and a pop-up flash, which are not included on this Olympus. (The micro four thirds sensor in the Olympus is larger than the sensor in the x10, though.)

I don’t like the supplied “slip on” lens cap, which is much bigger than typical snap on lens caps. The lens cap for the x10 is made of painted aluminum, and I immediately dinged mine by dropping the cap (not the camera) on the sidewalk while fumbling to put it in my pocket. Annoyingly, the lens cap┬ámust be removed in order to turn the camera on — even if you intend only to navigate menus and change settings on the LCD screen. To turn the camera on, you begin to rotate the rotate the zoom ring on the lens. To turn the camera off, you rotate the lens past the 28mm mark. Another reviewer speculated that users would be forever turning their cameras off accidentally while trying to zoom the lens. I don’t think that’s likely, because there is a positive tactile stop you can feel when you hit 28mm.

The fujifilm x10 offers approximately the same feature set as other compact enthusiast cameras, such as this (discontinued) Canon Powershot G9.

The Fujifilm x10 is not as pocketable as this Canon G9 Powershot, because the Canon's lens retracts completely inside the camera body. The Fuji lens offers significantly wider aperture, though. (f2.8 at maximum telephoto, compared to the Canon's f4.8.)

The x10 is approximately the same size as the Sony NEX 5 (or 5n, which has the same form factor) with wide angle pancake lens. The x10 is a bit taller, to accommodate the flash and viewfinder.

A more accurate size comparison between the Fujifilm x10 and the Sony NEX 5: Here the Sony is equipped with an 18-55mm zoom lens, which has a shorter zoom range and smaller maximum aperture than the Fujifilm x10. Why are interchangeable lenses so much bigger than zoom lenses on compact cameras? Because the larger sensor (like the APS-C sensor in this Sony) require a lens that can project a larger image circle, big enough to extend beyond the corners of the sensor with minimal vignetting.

One of the headline features of the x10 is Fujifilm’s EXR sensor, which promises to allow the photographer either to shoot at maximum resolution, or to sacrifice resolution for greater dynamic range or lower noise. In my limited testing of the x10, the EXR features have so far proved underwhelming. I will shoot some additional test photos and post them here with an update of this review.

Another frustration was the limited support for the x10’s RAW files. When I first received the camera, neither Adobe Camera Raw nor Apple Aperture supported the x10. So while I could shoot RAW photos, I could not open them on a computer. Today I downloaded the recent update to Adobe Camera Raw, and I was able to process a few images. I was disappointed to see that at ISO 400, photos from the x10 exhibited considerable luminance noise. I was also surprised to see that, though I had set the camera to shoot both RAW and JPEG photos, the images I shot in EXR mode were recorded as JPEG files only (no accompanying RAW image was recorded).

This JPEG image was shot on the Fujifilm x10 at ISO 800 using the camera's EXR mode for increase dynamic range. The dynamic range is pretty good, but the noise and JPEG artifacts are a problem for me.

The Fujifilm x10 offers a sweep panorama feature. Depress the shutter and slowly sweep the camera across 120, 180, or 360 degree panoramas. The camera takes several exposures and stitches them together. In order not to exceed the capacity of the buffer, the camera captures a series of standard quality JPEG images to create the composite. When you begin shooting a panorama, the camera's LCD shows a horizon line and uses the internal accelerometer to let you know if you're moving off axis as you sweep. This is a fun feature, but not one I'm likely to use often. If you want panoramic photos with better image quality, shoot a sequence of overlapping RAW photos and use the "Photomerge" feature in CS5 to stitch them together.
