Ok, so I got to thinking. Dangerous, I know. One of the things about the mFT format vs the FT format is the flange distance. This supposedly allows lenses to be smaller. I noticed that the lens diameter for equivalent mFT in comparison to FT is smaller. How is this? For a given f stop and focal length, the size of the diameter of the lens should be the same if the sensor size is the same. Or does this only apply to simple lenses or single focal length lenses. I guess what I am saying/asking, is that for a focal length of 14mm and f stop of 3.5, the diameter of the lens would need to be 39.2mm. Why does the lens diameter need to be larger for a larger flange distance, if the above situation is not the case?
