I am sorry this is a tad late, but I have been searching for information about ultra wide angle lens for my M5 which I bought about 18 months now. Accidentally came across your post, and so I wondered if zeiss biogon 21mm could fit into an M5 without breaking the meter swing arm, then perhaps the biogon 25mm f2.8 should fit in the M5 snuggly. Any enlightenment would be appreciated . . . .
