Tags: SLR Cameras Canon Last response: September 19, 2011 3:59 PM in Digital Camera Share jgibbs September 3, 2011 5:44:54 PM 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?

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. CompTIA_Rep September 19, 2011 3:59:50 PM I have seen a bit of Lag with the Sigma's (more so then canon). Otherwise, yes, good enough.
