The Fujifilm X-Pro1 is the latest entrant into the mirrorless camera market, with a 16.3mp APS-C sensor and a proprietary Fujifilm X mount. No low-pass filter (AA filter) is used over the sensor. Instead, the sensor is organized in 6x6 photosite blocks that have a high degree of color randomness to their CFA (Red, Green, Blue) filtration. Instead of RGRG on one row and GBGB on the alternating rows, we get this:
Basically, the sensor appears to be tailored towards resolution (and lack of color moire) at the slight expense of color discrimination. As with most Fujifilm cameras, the X-Pro1 supports the various Fujifilm "film simulations" and expanded dynamic range.
The X-Pro1 features a retro-based design with an hybrid optical/EVF viewfinder similar to that of the X100. Optical viewfinder magnification automatically switches from 0.37x to 0.6x for various lenses (90% frame accuracy quoted). As with the X100, the X-Pro1, the basic control design is highly retro, closely resembled the old Contax G in many ways. However, the camera is much bigger than the X100 (almost the size of the Leica M9)--it is not a small mirrorless camera.
The camera will have a selling price of about US$1700 and be available in March 2012. Initial lenses for the camera will be an 18mm f/2 (28mm equivalent), 35mm f/1.4 (52mm equivalent), and 60mm f/2.4 macro (90mm equivalent). Eventually, nine lenses will be launched, with the widest being 14mm (21mm equivalent). An optional metal grip will be available, a Leica M-mount adapter will be another option. The camera ships with Silkypix as the supplied raw converter (a slight step in the right direction--Fujifilm's own software efforts leave much to be desired).
