[quote name='Klaus' timestamp='1359806938' post='21710']It's always nice to see center crops. However, the key with something like the 17-40 is the border/corner performance.[/quote]
True, but I wanted to wait a bit and take time to test different Canon lens, the 17-40L, while it's fairly good in the center, doesn't perform very well on edges even on a real FF Eos, it shows strong vignetting, but it would be enough for me the adapter wouldn't make it worse, and using it at f/2.8 equivalent it's a real bonus.
