Some months ago I got a couple analog lenses for my cameras for a very fair price. One of those lenses is a TOKINA 135mm 2.8 for Canon. So, then I ordered an adapter without glass of EF on EOS cameras, for trying the lens on my Dslr cameras, mainly with the CANON 7D.
The thing that the adapter has not glass keeps the quality of the lens, but sadly it is not able to infinity focus, so it is able for doing some kinda macro photography, which i am giving a try, and I must confess that I like it. This lens, TOKINA 135mm 2.8 has such a good quality, mainly about the sharpness and the colour tones, it is nearly 30 years old but works perfectly.
Here you have some shots I have taken using the combo CANON 400D + TOKINA 135mm 2.8
