Which Telephoto to Buy?

Hi All:

I will be purchasing a 70-300 telephoto very soon. Either the Sigma APO DG or the Tamron LD Di. The small difference in price between them does not bother me. This will be for my K100D. Conventional wisdom seems to be that the Tamron is sharper (especially at 300mm) but has more CA & PF then the Sigma. However I have seen quite a few nice shots from both (however all were resized for the web). Anybody want to tell me which one I should get...and why? Thanks!

I own the Sigma, the Wife owns the Tamron. Both are good lenses, and the Tamron MAY be a little sharper at 300mm, but not by much, and the sigma is a little sharper in the 70-135mm range. I personally like the look and build of the Sigma better, and usually recommend it over the Tamron. You should be happy with either one.

Personally I'd take the Sigma because it has better Macro (1:2) than the tamron. From the Sigma site, the MTF graphs look pretty good too.

Anyhow I wouldn't normally link to a Canon forum but one of their members did a shot to shot comparision of the sigma and tamron lenses you were considering.

(Note the guy did cite possible AF error in the later images but it gives you an idea what the two are capable of.)

The Sigma arrived a few days ago. It's a very nice lens. Build quality is very nice. Here a are few of my first pictures with it.
