Customer Reviews

Best Walk-Around Lens You Can Find
When I purchased my A100, I wasn't too impressed with the Sony lenses that were offered, and I wasn't about to spend the cash on a Carl Zeiss. I had heard great things about the Tamron line, and the 17-50mm range fit well into what I consider a walk-around lens. The 2.8 max aperture is excellent, especially when paired with the camera-housed image stabilization in the Sony Alpha. I've shot hand-held in some really low light situations, with great results. I can't recommend this lens enough. If you decide to purchase an Alpha, go body-only and get this lens, you won't be sorry.

Very Pleased With This Lens
I am very pleased with this lens after breaking it in for a week on an Alaskan cruise. I relied on the len's wide angle capabilities more than I expected. The F/2.8 minimum aperture across the len's focal length range in combined with my Sony's A100 image stabilization to allow me to obtain many great low light shots that otherwise would not have been possible. Focusing was always fast and accurate.

perfect wide-short zoom
I'm very satisfied with this lens that has replaced the 18-70mm kit lens. F/2.8 is good enough for indoors at available light, so I use it a lot for casual family portraits. Then, when I go out I find its wide angle (25mm equivalent) to be very versatile for cityscape or street photography (I can even shoot from my chest, without looking through the viewfinder, at 17mm, for candids and stolen portraits). The best is that is not an expensive lens. For my style of photography, I don't find much need to change lenses. Also, it's a sharp lens to go with my A700. No complains.
