Purchased a Sigma 50mm 1.4 EX DG HSM from another member here yesterday. Crossing my fingers for a good copy. I had a Sigma 30mm 1.4 back in the day. Would get 7/10 shots good with it, so I was happy. *Most* of the things I shoot I'm amble to take 3-4 shots refocusing each time and sometimes at different apertures so I was never really disappointed. It might be a bit challenging to get sharp photos of my dog or kiddo when they are on the move but we'll just see.
I know there's focusing issues wide open. If mine is sharp at F2 then I'll be happy.
Canon 6D, 1100
Sigma 50 1.4 325
For a grand total of 1425 shipped to my door. I'm going to start saving for a 70-200 F4L I believe.
