All the lenses have aperture rings so it would seem other than focusing they should set the exposure or do I need to adjust the aperture in aperture mode to correct for exposure? I know NEX has a focus “peeking” mode to aid in that respect.
Thanks to all!
Brian, most everyone here uses the inexpensive chinese adapters without issue. Two of the more common trade names are Rainbow Imaging and Fotodiox.
If the lens you intend to use has no aperture you'll have to get an adapter that will adjust the aperture. You can identify these as most have a sliding switch marked "Open -- Lock" or something similar.
You don't get full control though, on my Pentax adapter I only get 5 discrete stops between wide open and fully stopped down.
I'm sure someone here has adapted Nikon lenses and can give you a more complete picture.
Holy cow! I have a Canon FD 70-210 lens that when I adjust the aperture ring, nothing happens. All this time, I never knew what that "Open-Lock" thing was until I read this. I tried it and I'm able to adjust the aperture ring lol
btw I'm using rainbow imaging adapter I got off amazon for like $25
