[QUOTE="BackdoorArts, post: 350056, member: 9240"] Yes, it is. The thing about it is that it doesn't get sharp until around f/8, which can drag up the ISO when you need to shoot at 1/1000 and above. My brother has the 120-300mm (Canon mount) and in his works, "At f4 it's amazing (sharp) across the entire range, and at f2.8 it's a solid 9.5". Stick a 1.7-2X on there and I'm golden and still brighter than the 150-500mm (which I still love). [I]Plus[/I] with the Sigma software you can configure it to calibrate focus at 4 points across the zoom range, so it's no longer about just focus calibrating on one point. [/QUOTE]
