I've been using Nikon cameras for a long time, and have a large investment in lenses.
I'm in the market for a digital cinema camera (e.g. Black Magic Pocket Cinema) and have noticed that most if not all entry level cameras (<$4000) work with Canon DSLR lenses, but not with Nikon.
Is there a brand/model that works with Nikon lenses? Is there an adapter for Nikon lenses?
