Hey everyone,
I'm new to this forum, and I had a question about a lens adaptor, I own a canon eos 50d and I'm getting a new lens from a friend of mine, but it is a AF-S NIKKOR
80-400mm f/4.5-5.6G ED VR lens. Can I use an adaptor for all nikon lenses? Are the mounts the same? Sorry for all the questions, just really confused on what I'm doing.
