Very good for the price
By A Customer
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.

Most used lens I have
By Warren Steffey
Forget landscapes, but for everything else these are my favorite lenses. I have two, because the focus function seems to be very easy to break. The first one fell about 16 inches from a couch to a carpet while in a camera bag, and the second one off a car seat to the car's floor and neither will now auto focus reliably. I really miss having a fully functional lens, but will probably look for a replacement on EBAY if they are this easy to break.

By Agent 007
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.
