Excerpt: great lens with pretty acurate autofocus for video. I would say the focal length range is pretty good on an crop sensor. I also have a 28-70 and i do occasionlly find myself wanting more in the frame. I believe this only works with aps-c cameras so you couldn't use the full frame on a full frame camera. I bought this mainly for video use and because of its completely quiet (it is quiet) autofocus which is pretty fast and accurate.
Pros: Fast / accurate auto-focus, Rugged, Strong Construction
Summary: Having owned the Sony 18-250mm, SAM 5018, and SAM 3518, this is the best solution that has both good image quality and portability without carry a bunch of lens with you. Another plus is that the autofocus is silent and quick so get ready for taking movies with faster autofocus and without hearing all the noise like the other lens mentioned above. It was well worth the money. If weight and focal length is not an issue, I would recommend having this lens in your bag.
Excerpt: I was looking for a great wide angle addition and I found it! Try the Sigma 17-50mm f/2.8 and I was very disappointed. I took the chance to pay more $ for this Sony 16-50mm f/2.8 and it pays off. It's a bit too big to handle easily, but nothing that you couldn't manage.
Summary: Great lens, fast and acurate operation. Great detail in pictures. Silent operation of autofucus. Great construction, wheatherproof. The lens is a little heavy because of the great diameter of the frot lens. The best lens for all propose.
Summary: This lens lives up to all of the positive reviews I have read. Crystal-clear focus and easy to use. Even nice bokeh for a zoom. It is a heavy lens, but the photographic results are worth the extra heft. Even the pros know about this lens as I have had a few who saw me with it give their thumbs up on what a good lens it is. I do wish that it wasn't quite so stiff on the manual focus, but I would rather have that than being too loose.
Summary: I like this lens a lot, it never comes off of my alpha 100, it is a way better lens than camera. It needs to be on at least an a700. It is fast accurate and well built. I got a real good deal on it, I did not pay retail. But for anyone looking for a new lens don't pass this one up.
Pros: Fast, color, build, DOF control.
Cons: Sometimes it searches more than I would like in low light, requires some post processing as far as some sharpening.
Excerpt: I am a long-time Canon shooter who recently received a Sony a65, so I needed a general purpose lens and chose the 16-50 2.8. The first thing I noticed was the build quality - easily Canon "L" quality. The focus motor is near silent, and it achieves focus very quickly. Image quality certainly did not disappoint, but I was also not blown away either. Bokeh is very pleasing, and sharpness is more than acceptable - with f/2.8 being very usuable.
