Summary: This lens does exactly what you would expect from it. I love it. I noticed that the quality of the pictures didn't get lost at all. The only problem that I found was that it was difficult to get a sharp image when I used the maximum (or close) zoom, but I developed my own technique to overcome this...
Decent lens for the price of $150 with A77. Not sure I would pay over $200 for it though.

Summary: Really 3-4 stars, but gave it 4. Pictures are not as clear as I would like throughout all zoom ranges, but this wasn't an expensive lens. Hey, about $150 with the camera (Sony A77) so can't complain at all.
Summary: I had a reasonably good experience with this lens. It's light weight, the image is very sharp for a APS-C lens, and the zoom range is very convenient at a decent speed. However, after a 2 1/2 years of normal use, the lens became blurry and the action sticky.
Summary: It got delivered at the estimated date. As soon as I got it I attached it to my Sony A65, and it works great, I'm in love with it, great for portraits. I test the lens with my front neighbors, damn, the zoom is surprising. Im still a beginner but Its awesome for me. Works just fine.
