Now I've seen some samples wide open and backlit, made with a state of the art EOS 5Ds R. http://www.sigma-global.com/en/lenses/ca...ssion.html I downloaded a couple of them and looked at it.

Some nice shots in there, thanks for the link.

Still, I wonder if there is a significant visible difference between f/1.4 and f/1.8 in these kind of shots. Or in other words: if a 20/1.8 would be fast enough to get 95% of the intended look.
