slow to focus

Nice lens if you like the fish-eye effect. Rezonably sharp. Got it because I can't justify the cost of Canon's EF 8-15mm.

Very slow to focus. I'm used to Canon USM lenses and this Sigma seems to takes ages to focus. Besides that the focusing ring rotates as it focuses so you need to be careful to keep you fingers of it as you handle the camera.
