Needless to say, I'm getting tired of waiting, so I want to build a kit around the T3i body and a high quality, general purpose lens, with the long term goal of eventually replacing the T3i body with the new 7D successor when Canon finally decides to release it. The camera will be used about equally for photos and video. I've narrowed my lens selection down to a couple lenses and was wondering if anyone here has had any experience with any of the lenses or just a general opinion on them would be greatly appreciated.
- Canon EF 17-40mm f/4L USM
- Canon EF-S 15-85mm f/3.5-5.6 IS USM
- Tamron SP AF 17-50mm f/2.8 XR Di II LD IF
-The two Canon lenses are roughly the same price +/- $40 at $700-740 each (the L series lens being the more expensive)
-The Tamron comes in at $500 roughly $200 cheaper then the two Canon Lenses, but has the advantage of a lower F-stop but no IS.
-An advantage of the L series lens would be that it would fit any new Canon camera where as the others are specific to the APS-C sensor but it also has the smallest F-stop at 4.
