I'm wondering if a medium format body with same F Mount would be possible. Now camera makers are squeezing more and more MP in the same 24x36 sensor because mainly of a "legacy" with old film and previous cameras.. But what about making a new sensor simply larger (30x45 as Leica S2 or whatever else) while keeping the same Mount? Would it be feasible? While DX helps a lot birders and sport shooters, a larger format would benefit landscapers and studio photographers. I know that the trend us now to make camera littler than usual... But ! Might ever exist an MX format where a 35 mm is already a wide angle and a 25 mm even more?
