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.
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.
Excerpt: I'm just getting used to this lens. I mount it on the sony a65. Previously I've had the 16-50 fixed f-stop. (which I Love) on my a65. The 16-105 is a fast focus and very sharp. It increases the range, and is a well-built lens. I will use it for landscape and possibly portraits. So far, I'm very pleased and I would definitely recommend it.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Lightweight, Nice Bokeh
The BEST "walk-around" zoom lens for the APS-C size sensor:
2 May 2013
Summary: I have the 18-200, 18-250 and the 18-270 and 3 other old smaller zooms... At first, I missed the 18-270's reach, but once I got acquainted with 16 end of the lens, I realized what I was missing... I was walking closer to my subjects. The 16-105 is the first that almost matches the picture quality of my 7 prime lenses, of course it can't match the open aperture of my 1.4 lenses, but it comes close at simular settings.
Summary: We bought a similar lens off craigslist. Was shocked at the difference between the lenses. This gives crisp clear pictures. It is a lot of money, but slightly blurry pictures aren't worth anything.
Best zoom lens for SONY Alpha APS-C cameras for this price
2 December 2012
Summary: This is definitely one of the best lenses for SONY Alpha APS-C cameras. It produces good pictures even at minimum aperture values for any focus lengths between 16-105mm. This is quite unusual for zoom lenses, especially with such zoom factor (about 6.56x). Most of them produce big aberrations and distortions - this statement is definitely not concern with SAL16105. It has fast-focus and good colors.
Summary: I got the SAL16105 used on ebay as an upgrade to the kit lens SAL1855 for the Sony Alpha a65. After a lot of research and comparison to the Zeiss SAL1680z, I decided to go for this lens. The primary reason was the cost and better range for travel use. Used prices for this lens are about half the price of the Zeiss. After a couple of days of shooting I am impressed by the image quality.
