As I wanted something wider on FF than the ATX-Pro 20-35mm F2.8 that I already had I picked up a cheap 14mm F2.8 Sigma. It was cheap because the focus is heavy (i.e. borderline for AF but fine for MF) but otherwise it looks in good condition.
On playing with it the lens seems ok when there aren't any bright lights in frame, but with them in frame the issues have to be seen to be believed - take this (shot at F8 I think) as an example:
Anyone else using the lens that could let me know if my lens is knackered of if this is "normal" for the lens?
Cheers
