For Sigma ...

OS (Optical Stabilization) is the same as Canon IS (Image Stablization)

I believe HSM is the same as Canon USM. But I've read that HSM not as quiet as Canon.

There is nothing wrong with Sigma lens. If you read around, some even think some non-Canons are better then Canon "L"s (I do not believe this).

That 28-135 ... I believe you can get those off EBay for around $250. They are kit lens for 40Ds and probably 50Ds.

Any EF and EF-S lens will be compatible with our rebels...so no need to worry :)

Yep - if you don't know how a "wide" 28mm is then get to a camera store and try them out if you can! Best place for it.
the only other option is to see if there is a local camera club you can join - chances are that there will be a few people there who might have that lens (or a simliar one) that you can see the effect on your camera

may be i will go to ritz and see if i can actually fit the lens on my camera before i buy one

That is why I said what I did..those lenses you have listed are still in the range of your 18-55 that you have listed in your signature. If you want to know how wide they are just put your 18-55 on and set it to the same focal distance as those two lenses you have listed.

LoL. Let me know which one you decide on. I've been kicking myself for the past two weeks with Canon 28-135mm IS UMS vs. Sigma 18-200mm OS HSM. I'm still in hell trying to figure this one out.

ahhh...simple...why didnt i think of dat...it seems to be wide enough...28-135 covers a good amount of distance with USM and IS...ive been looking at the reviews...all of them are pretty good
