Tamron really got a winner here, creating one fine zoom lens. So far I have been very pleased with it, especially with the vibration compensation, I love the way it really locks or frames the picture steady until you release the shutter. Overall it has a well built quality, a bit heavy at first but hardly noticeable after a while. The quality of the pictures is fine, clear and sharp. I would definitely recommend this lens for those looking to capture great pictures of their kids playing Soccer and Baseball, but it is also a great lens for capturing wild life as well. The only negative would be, that the lens can be distracting when is trying to focus, maybe annoying but not enough to stop using it. Great lens, thanks Tamron!
