Huh. I thought I'd have a leg up on this because I recently got an adapter to use my old Olympus OM lenses on my D5500. But I'll be darned if I can find any of the usual suspects - Adorama, B&H, etc. - selling Canon-to-Nikon versions. They ALL have Nikon lens to Canon body, but not the other way around. I wonder why that is?
Sorry buddy, I wanted to help out here but I've come up short. Hopefully somebody else will have better news for you. Best of luck snagging one!
