<p>Hello,<br>
I just bought a Canon nFD 17mm 4 in very good condition. I own also a Tokina RMC II 17mm 3.5.<br>
The Canon was supposed to be the the upgrade for the Tokina. I did some pictures just out of my window to compare both.<br>
I was shocked how bad the Canon was. There are a lot of informations in the web and people are saying the Canon is one if the best 17mm old wide angle lens you can buy and it is much better as the Tokina. The Tokina is very bad wide open, but the Canon as well. Stopped down to f5.6 and f8 the Tokina is the clear winner in sharpness, specially in the corners. The Canon is very mushy in the corners and it´s getting even worse if I stop more down. I think it´s a really strange behavior. Maybe something is wrong with the lens.<br>
What do you think?</p>
