Fujifilm announces that their much rumored return to Medium Format with the new Fujifilm GFX 50S camera and 6 new 'G mount' lenses. In the 80's and 90's Fuji produced the GX 680 6x8cm Medium Format film cameras. The new camera will have a G Format 43.8 x 32.9mm sensor with 51.4M pixels resolution.
The sensor is likely similar to the one seen in the Pentax and Hasselblad but in any case, it will be paired with the high-performance 'X-Processor Pro' imaging processor that will give the camera its own unique characteristics.
One of the main issues with launching a new format camera is to ensure there are sufficient lenses available to attract the professional to buy into the system. Fujifilm plans to have 6 new Fujinon G mount lenses available at launch. These will be GF63mm f2.8 R WR (50mm equivalent), GF32-64mm f4 R LM WR (25-51mm), GF120mm f4 Macro R LM OIS WR (95mm), GF110mm f2 R LM WR (87mm), GF23mm f4 R LM WR (18mm) and GF45mm f2.8 (35mm).
The new camera is a Mirrorless type with a detachable EVF viewfinder and an optional Power Grip with a unique trigger position for the Portrait mode controls. Availability will be early 2017 and price as yet to be determined but not cheap.
So at a time when Canon have decided, so far, to avoid medium format and Pentax have returned to full-frame (35mm), Fujifilm has bucked that trend to produce this new camera system. With Canon already being at 50M pixels on full-frame and Hasselblad being up to 100M pixels, 50M pixels look a bit light to me. Canon has 120M pixels in their locker and haven't stopped there. I know it's not all about pixels but it partly is and you need to be ahead of the game. It is a lot of development resource and risky venture. I hope it pays off for them.
