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. On the down side it's a little bit heavy/bulky (compared to the 18-55 mm) and I realized only later that my camera has a x1.5 crop factor so the lense is more a 24-157mm for me.
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". This lens is "slower" than it would appear.
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
Summary: Aside from this lens not reaching the lowest of low F-stops, this lens does it ALL. From architecture wide angle photography and landscapes to portraits of people and objects with high detail to the sports shot from across the field. you can capture everything. i was recently traveling for architecture and the ability to capture the entirety of a building is what set this lens apart from all my friends who were rocking the 18mm minimum focal length lens.
Pros: Wide angle focal length, and great zoom capacity.
Cons: i wish the f-stop was slightly lower maybe F2.8
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.
