RE: [LRflex] Re: a 4/3 sensor to match the 36mm size?I think a hinged mirror has been used before but I cannot remember who did it. I would think it would limit shutter speeds though. I would only seem to be an issue with some of the wide angle lenses with very rearward protruding rear elements and going from 24 to 27mm horizontal axis would only mean a mirror extending forward by 1.5mm. the total difference of 3 mm is divided evenly top and bottom. May not be a real issue with an R system?

Part swings up and part swings down? Or part folds under the part that flips up?
