EF mount vs F mount and adapter

[friedrice1212]

Hello, guys. I'm really looking into the Samyang/Bower/Rokinon manual lenses and I was wondering if there was any disadvantages in using a 35$ F to EF mount adapter from B&H and getting the Nikon F mount version of the lens. The reason behind this is that I have old Nikon film cameras and it would be cool if I can use inexpensive fast primes with them. If the EF version is significantly better on a 5D Mark II, I would go for the EF version.

Thanks!

My guess is that the SamBowRok Lenses have some special interior "mount" where the Canon/Nikon/Sony/... mount is screwed in. As the nikon mount has a longer flange distance, the F->EF adapter is a pipe with some dents at the right place.
There seems to be no obvious problem with your solution...
