So to make a long story short, the camera in the case, Alpha 77, to the Tamron lenses and this in in good hands, makes brilliant pictures ... of course all a matter of opinion .... autofocus too slow for me not an issue, each of can handle a camera, know what you have to do ... and speed is not everything, otherwise you would have previously never been able to make a good picture ... and quantity is not everything .... less is often more. Who wants to take good pictures, makes the lenses nothing wrong. Subsequent experience: After thousands of images has not changed the lens makes crazy good pictures, they would trade more against any other lenses.
