Summary: I bought this lens for my recently purchased Sony Alpha SLT-A99V. What a perfect "walk around" lens for a full-frame camera! The lens is superb from 28mm to 75mm. I use a Carl Zeiss 16-80mm lens on my SLT-A77 so I thought I might be a little disappointed with anything less.
Summary: A very quiet, well designed lens. It has become my go to lens for most applications. Great in low light and small spaces. The only drawback is the price...there are other lenses with similar features for much less. But if you are looking for a rugged, well made lens, this is the one!
Excerpt: I've used this lens at the Aquarium in New Orleans in very low lighting conditions with no flash, Sony A99, ISO of 1600 and handheld. The photos came out very sharp with no noticeable noise.I am very pleased with the results I get with this lens.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Nice Bokeh, Strong Construction, Very sharp images
Excerpt: This lens was purchased with my A850 Full Frame Camera. I also use it with my A700. The fact that it was design for use with the A850 indicates that it is a good lens as the A850/A900 cameras require the best lenses.
Pros: Compact Design, Easy To Use, Fairly light to carry, Sharp at maximum aperture, Very good on A850 A700
Excerpt: This is a great lens: nice and sharp even at f/2.8, and providing a very useful range of focal lengths for my Sony a55, from 42 to 112.5mm equivalent -- and all at f/2.8. Great for portraits, small groups at parties, and even kids' sports from the sidelines.
