I have Canon EOS system with some ring adapters to mount Contax and Yashica, Nikon F, Olympus OM, Pentacon Six and Exakta lens ..
I like manual focusing so vintage lens are not a problem.
Ususally i prefer the image quality of prime lenses.Is there something that have image quality near a prime in that focal range (about 80-150mm) with 2.8-4 diagphram aperture ?
