comment:This lens does exactly what I need it to do. I was looking for a fast lens to shoot horse jumping indoors, which means fast subjects in low-light conditions. This lens is perfect combined with the 7 fps at speed priority of my A550.

One thing that gave me some work was the very narrow DoF. This actually caused me to notice a slight error in mirror alignment. The misalignment caused front focusing which was very clear, and annoying, at large distances shooting wide open, missing the focus. After manual calibration of the camera, all my lenses now focus noticeably better :)
