Conclusion: I add another vote for this is a really a good one
Review: I have sony alpha dslr A200 and a bit disappointed with it's softness in focus. Now I know it was a problem of the lens comes with a default. With this Tamron zoom on it, I got a way better sharp images and I am really happy with my choice.

Conclusion: excellent zoom lens
Review: As I am not an accomplished photographer, I know little about all of the technical terms associated with photography. I do know, however, the tamron af 70-3-- f/4.0-5.6 Di LD Macro zoom lens for my Sony A-200 SLR Camera works wonderfully. Since I don't know what I am doing (yet) it has been basically a point and shoot experience that has worked out well.

Conclusion: Excellent lens for the price
Review: This is an excellent lens for its price. It's plastic-bodied, but of good quality plastic, miles better than any kit lens. The use of plastic also means it's light and thus easy to carry, where a heavier lens might get left at home. There are no rattles or wobbles even at the (quite long) maximum extension.
Flaws? It's slow to focus, which means that it may not be the best for fast-paced action, but this also helps with focus accuracy. The front of the lens rotates during focussing, which means that polarizing filters can't easily be used. Like all consumer zooms of this class, it's not all that fast, although it has a wider aperture at 70mm than most kit lenses.
Image quality on my Maxxum 7D is high, with excellent contrast and detail and accurate, vivid colors. The only real flaw is noticeable but not too objectionable chromatic aberration (CA).
Unlike many lenses advertised as having a "Macro" mode, this one is actually useful, permitting up to half life size at a reasonable subject distance. It's not quite true Macro, but is good enough for many purposes.
Fully retracted and with the hood reversed, the lens is usefully small, fitting in my camera bag without problems when mounted on the camera.
I'd strongly recommend this against competing lenses, especially Sony's comparitively mediocre offering.
Evaluation:
Conclusion: Lived up to expectations
Review: Have owned a Tamron lens before for a 35mm camera and were satisfied with that lens. Bought this to go with a Sony Alpha and it has met expectations. It allows quick, crisp shooting with very good detail in a variety of lighting. While it has given us some good shots with the camera handheld, it really shines with a tripod.
Our primary use is nature shots, but have used it for interior shots, as well. As advertised, it works very well with the autofocus capabilities of the camera. We bought it to enhance the capabilities of the camera beyond the 70-210mm that we already owned.
Be aware that the F-stop range is fairly narrow, but once you get used to it, performance is what we hoped for.
Evaluation:
Conclusion: Great Lens for Price
Review: A significant improvement over the older Tamron units. Good to excellent when two or more f stops applied. Slight purple fringing on highly backlighted subjects but easily removed in post processing. Overall, highly reccommended.
