I'm not so sure what the outcome will be but I think Canon seems to have pulled all the stops in miniaturizing the lens design. Typical back focus for EF lenses are in the range of 40-70mm range. But this one apparently has a "0.5mm" back focus. Which means an extremely rear plane ! Typically, a lens with a very close rear plane can be made smaller to cover the same image circle.
I wonder how this compares to other mirrorless systems or maybe even the Leica M system ? Anyone has any clues what are the back focus of other mirrorless systems like the NEX ?
18mm for the NEX. Here's a list of ALL lens mounts http://en.wikipedia.org/wiki/Lens_mount
