Cannon users will say that the size of the mount will limit the max possible design speed of a lense. It has been pointed out to me quite clearly, by Rob, that the Leica M mount is quite old and happily supports the Noctilux 1.0. In terms of physics it only matters how the light is bent with repect to the position and size of the last element. The myth of the EOS series of Cannon SLR's is also another furfy. I often hear that the mount was redesigned to make it possible to implement faster lenses. That is another scientific method of extracting several new lense sales from bummed FD owners. A M leica and an EOS camera are available with a 50mm f1.0 lense. On the other hand, having owned a Nikkor 55 f1.2, I can conceed that the mount is looking a bit tight. > i owned the lens and the 7. the .95 mt is on the outside of the the ltm, > just as the contax ll mt had an inside and outside mt. the reason for the > outside mt on the canon 7 was the enormous weight of the .95 plus the fact > that threading it into a ltm would have reduced its effective aperature.
