Tamron 17-50mm Non-VC for video

I have been looking at the Tamron 17-50 and the Sigma 18-50 for my T2i.
Outside of the wider focal length, what makes people choose the Tamron
over the Sigma? Having been brought up on Zeiss and Canon lenses, the
reversed direction of the focus barrel (reversed to me, anyway) makes me
think i'll drive mysefl crazy with the Tamron when focusing on the fly-- I am
curious to know why more people seem to favor the Tamron.

from www.the-digital-picture.com :

"The differences? The Sigma flares more easily. The Sigma shows more CA. The Tamron is noticeably wider (17mm vs. 18mm). The Tamron focuses faster but the Sigma focuses more quietly. The Tamron focuses much more accurately - My keeper rate is far higher with the Tamron. My Sigma has a weak left side - For sharpness, the Tamron beats the Sigma easily on the left side, but the Sigma is slightly better on the right. The Sigma rings rotate the Canon direction, the Tamron rings rotate the opposite direction but with less effort. The Sigma is less expensive (but not by much). The Sigma's requires its lens hood to be removed to install/remove the lens cap. My choice would definitely be the Tamron 17-50mm f/2.8 XR Di II Lens over the Sigma. "
 
I've had that error a number of times. I don't think it's any big deal, but yeah... it is a bit disconcerting.. I just undo the lens and re-click it and it works again.

I think maybe on the Tamron, it just doesn't interface quite as well as my other lenses.
 
Hellp!

I just got the error 01 message on my Canon t2i and the Tamron 17-50 2.8 non VC. And it's not going away!

Tried all of the above (undoing lens, reclicking, waiting etc) but no go.

Do I send in the lens for repair of what?

It was behaving fine for about a month since I bought it (used, but new condition).

Any suggestions?
