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.
Excerpt: I've had this lens now for a few years on my alpha55......now on an alpha65. A major step up from the kit lenses and i use it 99 percent of the time. Sharpness has been overall very good and I use It with confidence.
Great kit lens, Sony's should come with this standard.

Summary: Probably my favorite "first lens" for any kit. I sold my Nikon system and bought a sony dSLT and had to start over. This lens was my primary choice as I shoot 95% of all shots with this lens. Excellent range for the price and very nice quality/sharpness.
Summary: I have had this lens for a while, and these are the only cons i found. There is vignetting on some of my images, distortion on many, in some cases struggles to find focus, and very loud when it does. This lens is nice for a first lens, but definitely not a pro lens. These are my warnings.
Pros: zoom, design
Cons: vignette, struggles to find focus, noise of focus, distortion
Summary: Great range of coverage; this is one of the best all-purpose lenses I own…. it does get a bit heavy at the end of a hike, but performs well… I have to note and agree with other reviews that it is a bit louder than my other lens when it zooms but the performance of the lens gets me to look past it.
