Pros Amazingly well-built, full-manual controls, fast, gets out of the way, looks great
Fujifilm's film heritage shows when it comes to the JPGs
Cons Dodgy RAW conversion support from third-parties.
Summary The Fujifilm X100S Costs $1,200 (I got it for way less by trading in a bunch of old Nikon lenses and an SB900 flash), and is worth every penny. It's the first digital cameras I have used that comes close to being as good as my old Leica M6. No, it's not a Leica, and it doesn't have the look that comes from Leica's amazing lenses. Then again, the M9 costs ¢9,000, plus a few grand more for a lens.
To call the X100S a "Leica-Lite" is unfair. What Fujifilm's designers have done is start with the same concepts as Leica's M-series designers (all long-dead now, seeing as Leica hasn't had a new idea in a century) — a shutter dial, an aperture ring, a small body and prime lens and a big, oversized optical viewfinder — and built a modern camera with them.
There's even a hint of Apple-like compromise in here, leaving out many features so the remaining ones can be better: The non-changeable lens is the most obvious of these, banking on the fact that most Leica-shooter never used anything but a 35mm Summicron anyway and using that knowledge to keep the camera small and light.
Pros Photo quality
High ISO awesome quality
Fast auto focus
Control wheel is a little too sensitive
Summary It's a great camera. Maybe not for a beginner, but it's perfect for taking with you when you don't wanna take with your heavy DSLR
Pros Excellent resolution and detail in photos
Low noise up to ISO3200 and above
Excellent colour reproduction
Unique optical hybrid electronic viewfinder
Aperture / Shutter controls
Excellent build quality
Silent shutter sound
Bright f/2.0 lens .
Cons RAW not available with "Advanced Filters".
Summary The Fujifilm X100s improves quite dramatically over the Fujifilm X100, with a new 16 megapixel sensor that delivers excellent noise performance and detail in photos. The X100s gives the same familiar controls as the original X100 as well as a higher resolution electronic viewfinder,
The camera has a bright f/2.0 35mm equivalent lens and as long as you are happy with this focal length then the camera would make an excellent choice, delivering extremely high quality photos. The Fujifilm X100s is priced somewhere in the middle of APS-C compact cameras, and for many happy X100 buyers, the X100s will deliver many useful updates, including better image quality, a better EVF, quicker controls and response, although the price is likely to put some people off. For those that have the money the Fujifilm X100s is highly recommended.
