Wondering if anyone has done comparisons of the EOS 50mm 1.4 to the Sony e-mount 50mm 1.8. I realize the 50/1.4 opens up wider, but it's soft wide open, so I usually stop down a little bit. Let's say both at 2.0 and beyond. Anyone have any comments on the EOS on one of the newer Canon crop sensors vs. the SEL50 on say a NEX6? Also, how is the AF of the SEL50 on a NEX6? I already have EOS lenses, but just got an EOS to E adapter, but the AF is unworkable, so I'm wondering if I should just "go native" with the emount lenses. Thanks for any help.
