Excerpt: First year lens worked great. Photos of all kinds in doors, outdoors, poor lighting bright light lens performed as expected. Soon there after lens auto focus continuously. It was always searching. Even after locking in it would try to adjust again. Using it on a A57.
Excerpt: I picked up this lens to use as the only lens on an African safari which has strict weight limits on luggage. I tested it out on a trip to the UK and used it indoors, outdoors, in all sorts of lighting conditions.
great travel lens! I only carry one lens now! Also, a great lens for professional work or action photography

Summary: I bought this lens for my Sony Alpha 77 camera to replace an older 18-105 mm lens as my standard "shoot all travel lens" and I was not disappointed at all. The focus is spot on and there is very little image distortion when shooting wide angle photos in horizontal position.
Excerpt: Sony only has a warranty of 1 year for this lens. I had this lens for 2 years when suddenly the autofocus failed. When I called Sony their response was to buy an extended warranty plan next time. Says a lot about their quality and support. I take exceptional care with all my photo gear.
Pros: Great Lens When It Works
Cons: Failed After Two Years, Lens Lock Position Useles, Lens Slippage Critical
Summary: I purchased this lens to use with Sony a57 in May 2013 and have been happy with the results. The range is great and has produced good results. As others have pointed out, there is noise from the auto focus when shooting video.
Summary: I bought this lens used for a trip to allow me to stop the ever changing of lenses for different purposes. I have taken lots of applications and am in heaven with this lack of change. It has exceeded my expectations as an avid amateur photographer.
