Any compelling reason to sell my Canon 17-40 L for the Sigma 17-50 OS. The price is about the same currently. Is sigma 17-50 f2.8 OS better than the 170-40 F4.0 L other than the extra stop? Anybody who has experience with both, please chime. Thanks in advance for your advice and comments?

I have both.
The Sigma is great, some say L quality.
I appreciate the extra stop, the stabilization and the extra 10mm of reach.
My 17-40 hasn't been on my 7D once since I got the Sigma.

There are several better standard zoom options for a crop body than the 17-40L, and the Sigma is one of them. You get image stabilization, more focal range, and an extra stop on the aperture.

The 17-40L was designed as an ultra wide angle lens for a full frame camera. That is really it's sweet spot.

I just upgraded from a very capable Tamron 17-50mm non VC to the SIgma and ma very happy. The Sigma AF is better.

Oh I forgot completely. Will the Sigma 17-50 work with 5D Mark II or Mark III or will there be vignetting at the broader end? Well, that will be a dealbreaker for me if there is vignetting because 17-40 on a Mark II has none. For what you all have mentioned, the sigma is for a crop body and not for FF, is that right?
Thanks for all the replies, folks.

The Sigma 17-50 is for 1.6 crop cameras. Yes you will have vignetting on FF.

Don't forget you get better weather sealing with the 17-40 (when you seal it up with a filter) ;)

Sigma, no doubt :) For crop, Sigma can do f/4, super sharp for me & OS also is a plus, if not going to FF route..
