I'm suprised by one of the others reviewers quality problems. I have pointed the camera both straight up and straight down and the zoom and focus do not move one bit - it is dampened very well. I almost wonder if they are referring to a different model. The lense seems to be high quality and the autofocus is fairly quick and quiet for a lense in this price range. I would definately recommend it to anyone.

For the price this lens gets the job done. Stopped down to f/7.1 - f10 gives amazing sharpness. As far as I can see there are no chromatic abberations. Focusing is very quick compared to the Tamron 70-300. The Focusing motor is a little noisy. I'm using this lens on the K-r. Because the K-r has a high ISO range, in low light I shoot at ISO 5000 with good quality and no problem. High ISO ranges eliminates the need the for the very expensive f/2.8 lens hype. I'm a wedding photographer and my lenses put in alot of work so I'll update my review soon.

This is an awesome lens! and so compact. The quality is just great and the price is so reasonable...absolutely no problems here! I highly recommend this lens!
