Today I met with one of my brothers, and he got some very good lenses made by Tamron: 70-200mm, 18-70mm, 200-650mm.
All of these lenses are from 1985-1999. I know that these lenses are compatible with Nikon. All of them are manual focusing and made for film SLR cameras.
But, are they compatible with my Nikon D5100 DSLR?
I did quick research online, and found that some "Adaptell" can be used to attach the lens to Nikon — but are they available for Nikon D5100?
Please tell me in detail what I need. I extremely need those lenses for online photography courses.
