Hello! I'm new to the forum, and recently decided to switch from Nikon back to Canon. I always had Canon film cameras, but when I switched to digital, I dabbled in Nikon. I loved the Nikon, but there's something about Canon that brought me back. Sooo, today I got a great deal on a used Canon 20D, and I have always loved these cameras, so I had to do it. Unfortunately I sold all my Canon glass after the switch, and have a bunch of Nikon glass. I have had several people tell me, to just pick up some adapters to fit Nikon lenses on the EOS bodies. I have never used one of these and have no idea if they work well, or if it affects quality at all. Also, does this work for all Nikon glass, or just specific models? Would work for the AF-S lenses as well? Anyone with any experience with these, please let me know if it's advisable or beneficial to be able to interchange the lenses.
