Your comment about shallow DOF is right on--this is a potential limitation of the Tamron. But of course, you don't have to shoot at f/2.8 all the time.
IS is really neat, but as you probably know, it doesn't help a bit when it comes to subject movement--only camera movement. The only thing that'll stop subject movement is a faster shutter speed, and you can only use a faster shutter speed if you can let in more light, which means that the Tamron has the edge here.
I have the Tamron and think it's terrific. I used to have the Canon 28-135 but sold it.

Both great reviews, i'm pretty new to photography and I don't really understand how the IS would help in a low light situation. Either way I'd probably have the aperture opened up all the way in a dark club, with the IS you can shoot slower shutter speeds which lets more light in.
I understand how this helps you get a better exposure but with slower shutter speeds you get less stop-action so even if the object is correctly exposed wouldn't it still be blurry (say a guitarist strumming in a dark club) Most the time in a dark club I assume i'd be shooting wide open aperture so that would go back to the 2.8 DOF problem again, what's the best solution?
Also, as far as the zoom being harder to move is this a normal Tamron attribute compared to a smoother zooming Canon lens? IT really bothered me that i had to twist fairly hard to get the lens to zoom in/out compared to the 28-135 lens. Oh yeah on more thing, is the IS a mechanical function or does it require electricity, i'm assuming the lens has it's own battery for the IS motor?
