Originally posted by konraDarnok the canon fdn lenses used in that link are full-frame lenses, not "non-ff lenses/adapters", as the page title says... maybe it's an english translation problem? because those lenses don't need a focal adapter, i can't see the logic behind adding another layer of glass, if that's what is happening there... of course, since we are looking at weird combos, lol...
in addition to using certain aps-c lenses on full-frame cameras, some aps film lenses will work on the a7/a7r... i tested it with ix-nikkor lenses from nikon pronea cameras:
Nikon IX-Nikkor APS film camera lenses mounted on Sony a7 a7r NEX e-mount cameras
i looked at the 30-60 lens there, that lens takes a full-frame shot with some vignetting, but it's usable... the better option for a cheap junk super-light zoom is the ix-nikkor 20-60 lens, because it gives you a usable 24mm focal length, on a full-frame camera... the 20-60 that i shot with had some possible focus distortion issues on the right hand side, but the center area was plenty sharp on the a7r... unfortunately that uneven frame issue means that i've basically struck out on both ix-nikkors.
here is that 20-60 pic, at 24mm focal length, unfortunately this forum won't take the full-size:
