Fujifilm Finepix S100FS Review

Pictures from the Fuji Finepix S100FS are amazing. This camera produces images with extremely low image noise. While this is normal among modern digital cameras at low ISO, this one keeps noise low up to ISO 800 while retaining a good amount of details. At ISO 1600, noise becomes intrusive and starts eating away details. Still, small prints look good at ISO 1600. ISO 3200 is not much noisier but somewhat softer. A usable small print can be made from ISO 3200 and even 6400. It won't be so clean but, at those ISO sensitivities, this is a great performance.

Enhanced dynamic range is a big selling point of this digital camera. Frankly, it is surprising that only Fuji has been advancing on this issue, it should be important to any camera. The Fuji Finepix S100FS uses sophisticated firmware to extract up to 400% more dynamic range from its SuperCCD. The great thing is that it actually works. The Fuji S100FS can capture more dynamic range than any fixed-lens digital camera.

Exposure is also excellent with less need to use EC than most cameras. This is somewhat helped by the camera's expandable dynamic range too. As dynamic range is increased, the Fuji S100FS adds to highlight details more than to shadow details. Since the camera knows what the luminance distribution of the scene is like, at can choose the dynamic range automatically.

Color reproduction of the Fuji S100FS depends on the chosen film-simulation mode. In Provia mode, which is the default, colors are realistic but a bit undersaturated. In Velvia mode, you get bright and saturated colors. It is technically oversaturated but not overdone. Soft mode gives natural colors with less contrast and gives a slightly darker image overall.

Another great asset is the 14.3X stabilized optical zoom lens of the S100FS. It is exceptionally sharp throughout its focal length and degrades very little towards the corners. This lens starts at a bright F2.8 maximum aperture and diminishes slowly as it is zoomed in. It only drops to F4 past 200mm. At the telephoto end, the maximum aperture is F5.3 but that it at 400mm.

The problem with most Fuji lenses, including this one, is pronounced chromatic aberrations. This shows up as wider-than-average fringes of purple. On the other hand, although such aberrations are larger than with most cameras, they do occur less often. The expanded dynamic range probably helps because chromatic aberrations are found in areas of over-exposure which themselves occur less with the Fuji Finepix S100FS.

The performance of the Fuji S100FS is reasonable, but far from stellar. It turns on in about 3 seconds, which is average. Focus speeds are good, taking between 1/2 and 1s, on the telephoto end. This is not class leading as other ultra-zooms focus faster than the S100FS. Once pre-focused, shutter-lag is very short. In shooting mode, all controls respond instantly. Shot-to-shot speeds are about average for a high-end camera, about 2 seconds.

Entering and exiting playback mode is quite fast. Since this is a shooting-priority camera, it instantly goes back into shooting mode when pressing the shutter halfway. Although scrolling through images is fast, it takes about 1 second for the basic image info to appear. Pressing any button other than the left or right arrow while info is not displayed has no effect. This is the only aspect of this camera's performance which is slow. The S100FS uses a proprietary lithium-ion battery. The result is that battery-life is short for an ultra-zoom.

It is clear that the Fuji Finepix S100FS delivers superb results for a fixed-lens camera. Image noise is very low, dynamic range is outstanding, color is good, exposure is excellent and its lens is very sharp. This camera is also reasonably fast, without being the fastest though. This is a well-built camera with good ergonomics. The S100FS is also quite capable, with a mechanical lens and optical image stabilization, a complete set of manual controls and several unique features.

While it may not be perfect, there is little not to like about this camera other than the use of a small viewfinder and the use a lithium-ion battery. The dilemma with this model is that its size, weight and price makes it comparable to a DSLR. Some people even mistake it for a DSLR!

Thinking about the compromises between a DSLR and a fixed-lens camera in general, the core compromise is mainly image quality and speed vs size and price. With the Fuji Finepix S100FS, you get a fixed-lens camera at the price of an entry-level DSLR with a similar weight. Even though the image quality of the S100FS is superb, DSLRs still do better. The biggest gap though is in terms of speed. Even an entry-level DSLR is significantly faster than the Fuji S100FS. However, the S100FS has several advantages. The biggest advantage is its integrated lens which covers 28-400mm. A comparable SLR lens, such as the Pentax DA 18-250mm F3.5-6.3 is still half-a-stop slower and not as sharp, so you get better image noise but lose on details at some focal-lengths. Obviously, a DSLR can accommodate a set of high-quality lenses that will trump the S100FS but that adds much more cost and weight. Then there are other features common to fixed-lens cameras such as live-preview and a movie-mode.
