It can be difficult in low light situations. I'd say to avoid any sort of motion blur hand held with a full frame camera, you should be around 1/800 minimum. So daylight is fine. I use it with a tripod all the time though, so I don't really run into the issue too often. That photo was taken at 1/80 second on a tripod. And man, that lens is REALLY sharp. Pic related is a 100% crop of that image
