Is Canon EF 24-70mm f/2.8 L USM Lens that much better than Sigma 24-70mm f2.8?

Question

I am looking for a 24-70mm f2.8 lens for general use and low light gig/concert photography.

The 2 I am looking at are:

Canon EF 24-70mm f/2.8 L USM Lens

Sigma 24-70mm F2.8 IF EX DG HSM Zoom Lens

The Canon is almost twice the price of the Sigma. Is it worth paying for for the Canon? Which lens is best

Answer

Absolutely. With most lenses, the old saying 'you get what you pay for' applies. If you want to buy a good Sigma lens (they have some excellent ones), you'll have to buy an expensive one.

Between these particular models, the Sigma is much softer near the wide-angle end and has stronger fall-off as well. At the long end, it diminishes but you have to stop it down a few more stops than on the Canon.

The Canon unit is also weather-sealed against the elements, dust, moisture, rain and snow, when used on a weather-sealed DSLR.
