When I first switched to from Nikon to Canon I only had Nikon lenses. I used this to adapt the nikon lenses for my canon body. Its a really high end lens adapter and is in solid 9/10 condition (the only reason I put 9 is because I've used it, I think its still fantastic). I put the link above (https://www.bhphotovideo.com/c/product/724050-REG/Novoflex_EOSNIK_NT_EOS_NIK_NT_Lens_Adapter_for.html)

I can provide pictures upon request but its mainly a mechanical thing. I would suggest trying it on instead.
