Full Frame NEX new SR5 rumor

the new lecia M is pretty 'modern' since it's announced only a couple month ago,

the flange distance is around 27.8mm, well not as awsome as mirrorless at 18mm, it is considerably less than the usual dslr

then again, comparing dlsr with mirrorless is comparing apple to oranges, the fundamental difference for me is still the AF speed, once that gap disappears, we can get a better comparison.
