Summary: Auto focus is really slow. But once you find the right range photos are really sharp. However, if you are just starting out in photography, you may want to learn the basics so this lens won't be such a test.
It's better than some of the higher priced competition.

Summary: I wish it had some sort of Image Stabilization. But I can't really complain too much. It's a great lens. Has good glass and is supposedly fast. But hand held indoors your gonna need a tripod to get nice sharp images.
Summary: This was the best product i ever bought on ebay!the service was awesome! Its a perfect lens thought its weekness relies in its autofocus! I encourage others to buy this lens as it is a good one for the price paid!i have made several shots with it and im quite really happy!
Summary: I have in my camera bag a few Tamron lenses that I am happy with and so was confident I would be happy with this one. However when I got this one I had a few disappointments with it. First, the quality of the photo was not up to par with the other Tamron lenses I have.
Excerpt: Très bon piqué à toutes les ouvertures, m^me en 2.8 ! Il faut juste s'habituer au mouvement des bagues et à l'inverseur Auto / Manuel, à conseiller sur un Pentax puisque le boîtier est stabilisé.
