BUT - if you have a sensor that's less than 35mm full-frame, you have a magnification factor for the lenses you use if you're using 35 mm lenses. For instance, the factor for the 4/3 sensor is just under 2x, which means that to get a 35 mm equiv of a 100 f 2 macro, you're using a 50 f2. What that means in terms of whatever body becomes available for the M lenses is that we won't be using them at standard focal length - and we won't have any real wides - For instance, if the factor is 2x, the 21 2.8 becomes a - ho hum - 42 2.8. The 35 1.4 becomes a 70 1.4 - which will be a great lens at a weird, in between focal length...the 28 f 2 Summicron becomes a 56 f2 - sharp as a tack, but not a great 28 any more...and so on. And if you want anything wide at all, you're only real option would be the Cosina 12 f 5.6 that isn't rangefinder coupled...and it would give you a 24 f 5.6 without rangefinder coupling....Soooo...There are advantages to larger sensors that have nothing to do with image "quality." And while we don't know what size sensor this Cosepson will have, it's probably a safe bet it won't be full frame.... B.

Good answer. Cosina has certainly shown itself to be agile and Leica not so. I haven't heard any real evidence that Leica is holding out for a full-frame 35mm sized sensor. The 35mm sensor doesn't appear to be an obsession with Canon and Fuji. The 35mm size seems to be an arbitrary sized based on film cameras. Digital is a new game. Sam S B. D.
