Tamron is really throwing their name around with the new lineup of VC lenses. The above video is one of the tutorials found at the Tamron Youtube channel. I actually own the same lens shown in this video (if that's the 18-270mm), and have to admit it's one of my most favorite travel lenses. The VC I can vouch for, works awesome, and works well for video too. You won't get the super sharpness of a prime and the focus ring is a bit noisy and stiff, but Tamron is doing a great job with their pricing too.
