Hello, I have a Mamiya 645 200 f2.8 apo and mamiya 645 150 f3.5N. I would like to use these lens with my Nikon D700 as well as Canon EOS 60D. Can anyone suggest me which lens adapter is good for my camera body and the lens?

I bought Fotodiox last 1-1.5 years ago (M645 to NikonF lens adapter pro grade). I don't like it much because between Mamiya lens and the adapter is not connect securely well in my opinion.

I also have a Pentax 6x7 300 f4 ed(if). I also would like to buy an adapter for my cameras too.

I'm looking for a good quality of a lens adapter. Please suggest where I can buy from.

Thank you very much.
Best Regards,
