Tamron 300/2.8 LD IF SP AF Telephoto Lens vs the Sigma 300 f2.8

Which one would you get? The Tamron seems to get slightly higher reviews. So I am being swade that way so far. Has anyone used both of these lenses?

I have tried both, but not extensively, and didn't buy either one. The Tamron seemed to distort a bit more in the corners. The Sigma was a touch "warm" in color, which is good sometimes. Both of them focus a LOT slower than the Canon 2.8 or even the Canon 4.0, and slow focusing isn't so good sometimes. If you can't afford the Canon 4.0 (cheaper than the 2., then I'd have to say get the Sigma. I thought it was a click better.

I think the Sigma 300mm f/4.0 is better than either of the two you are comparing though...

Try the latest Tokina AT-X Pro 300 f/2.8. It apparently focusses very fast and is only a hair behind the Canon 300 f/2.8L in image quality. Dirt cheap as well. It scores much better than the Sigma or Tamron.

Don't forget Sigma's 120-300 f/2.8...its zoom range are handier than a shirt pocket...optically, it's a superman! AF might not totally match up with Canon, but it ain't slow either...
