I'm using my 24-70 currently and doing some HDR with the Sun in the frame. But it seems to me that flare performance is holding my results back either a tad or a lot. Not sure because I don't exactly know what the best of the best in this category can achieve. I'll post an example later. I ALWAYS use the lens hood BTW.
What should I be thinking - 45mm PC-E? Anything else zoom or prime for full frame?
I actually have a 50mm Sigma, anyone happen to know how that is for flare?
