Here is something interesting that is coming from this year’s photokina. Fuji just announced the GFX 50S. It is a medium format camera with a sensor that is 70% larger than a full frame DSLR.
The sensor for this new camera is a G Format 43.8 x 32.9mm sensor, and it will shoot in the following aspect ratios: 4:3 (default), 3:2, 1:1, 4:5, 6:7 and 6:17, which were available in large and medium format film cameras. The processor will be a new X-Processor Pro (I don’t even know what that means yet). Since this is a mirrorless medium format fuji were able to create a short flange of just 26.7mm (sensor to lens distance) to shorten the back focus distance as much as possible. This prevents vignetting to achieve edge-to-edge sharpness of the world’s highest level.
