Super fast lens to a super price

Nevertheless, here are a few negative points:

I run the lens on a Sony Alpha 65. Here the lens is such a high speed, the fastest shutter speed (1 / 4000s) is still too long and the images are partially to light in the summer with plenty of light (... rather a shortcoming of Camera)

The sharpness differences between center and edge can handle me, because I usually use this lens for shooting large aperture and high shutter speeds.

When recording video you can hear later on the video autofocus, manual focus here makes more fun

Every now and then the autofocus makes problems (possibly up are equipped with a FW upgrade)
