Excerpt: Purchased the 16-105 for our recent trip to Arches, Canyonlands & Dead Horse. The lens never left the a57 the whole trip. Used for wide angle & panoramic and with the built-in multiplier on the 57; reaching was not a problem either.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Good Glass For The, Good Glass For The Money, Rugged, Strong Construction
Excerpt: I use in in Events, Street Photos, Sports and Fast action assignments. I can focus at 16mm and zoom in on detail very quickly without losing anything, and can do it fast. Not good enough for me for Movies, and portraits
Pros: Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Rugged
Excerpt: Bought this to use on vacation in lieu of my 18-55. Substantial construction. Beautiful color on landscapes.....even photographed whales breaching and got pretty good detail. Didn't let me use shutter in some auto modes, but in manual, even for an amateur like me, a good all around lens.
Excerpt: This is the first lens I bought (after the 18-55mm that came with my a65). It's a really good travel lens, allowing you to shoot a wide range of pictures without having to constantly change your lens. Great picture quality/colors.
Summary: This has become my primary lens on my A580. It covers most of the range that I need, with the exception of long range wildlife photos. The images are very sharp at full magnification, nearly as sharp as my best 50mm prime lens.
Summary: Advertised as f/3.5 - 5.6. At 16 mm focal length, the maximum aperture is f/3.5. However, at 24 mm focal length, it jumps to f/4.5, and at 35 mm focal length, it jumps to f/5, which is disappointingly "slow", This information is not available in the "specifications".
