Originally posted by GibbyTheMole Not to throw cold water on the OP's idea, but having to mount the lens to a DSLR to set the aperture sounds like a big pain. Personally, I'd pick up some cheap lenses you didn't need to do that with. C-mounts, Pentax K, M42, or M39 lenses are a few that have worked well for me.
I have two lovely M42 lenses (Jupiter 9 and Jupiter 37A) with manual aperture, and the 25mm/1.4 C-mount you see so often on eBay, and have had the Q adapters for them for a long while.. BUT, I have a big stack of Canon EF and EF-S lenses that I work with on my D-SLRs (10-22, 28 2.8, 50 1.8, 60 Macro, 80-210 4.5-5.6, plus barely used 17-55 and 35-80), so for the cost of an adapter it's fun to try them on the Q. Sorting the aperture that way does sound a pain, and for that reason I'll probably shoot them wide open often (at least, for the purposes where it doesn't matter if they're a little soft due to being wide open)
