I am buying a Canon EOS T2i and would like an all-purpose lens for vacationing. I am torn between the Canon 18-200 lens,which has IS, and the Sigma 18-250 lens, which has OS (although they describe it as Image Stabilization. Is it the same thing?

Yes, it is. OS is Optical Stabilizer for sigma.

You can check the review here http://www.ppmag.com/web-exclusives/2009/06/review-sigm...

One thing is that Canon is more reliable than the Sigma, though again, they all performed good enough. I use the canon IS lenses and I like them.

Have fun.

I have seen a bit of Lag with the Sigma's (more so then canon). Otherwise, yes, good enough.
