I love this video! He is getting the most of what he does, and does that as much as he can..
Expect it will work fine at the dark bar party shooting - with no flash! I have 50mm Art and I'm very happy with picture it produces at f/1.4.
As for SONY A 7s - I have an increadible high ISO test results: https://plus.google.com/u/0/113540123829280887772/posts/CKuXBfAh42Y?pid=6073189452363714706&oid=113540123829280887772
I have bought it and - oh, no! One side has 1/4" and the opposite - 3/8" thread. How is it supposed to be put in between monopod and a ballhead, that sits on monopod??? Guyes, get me the right one!
Looks like a goog compact companion to a full-size Canon DSLR to share lenses.
