I don\'t understand this comment, or does the DOF preview button have a function I\'m not aware of for a manual aperture lens?
my (limited) experience suggests to me that canon cooks the metering with oem ef glass, as I think all my non-oem meter poorly from 1.4-2.8, give or take.
I\'ve only tried this with a few fast EF primes, but if I twist the lens a bit so the contacts don\'t mesh, I\'ll get different metering by at least 1/2 stop.
No, the remark about the DOF preview button is misinformed, I believe. It doesn\'t do anything when using an alt lens, with chipped adapter or unchipped.
