Title: Impressed by IS feature
Review: Just a short blurb on how impressed I was by this lense's IS feature. I have IS on the 3 other Canon lenses I have. All state they should eleminate up to 3 stops. This lense is obvious that it works to that level. I put the movie mode on my T2i and you can really see the amount of shake the IS takes out of the image. Very impressive. Only negative I can give this lense is that the IS mechanism was audible. You really notice when it's working with a slight hum from the lense. You don't hear it out and about, but in a quite room it took me a while to figure out where that new noise was coming from. Auto focus usually makes noise, but this is the only lense I've used that hummed while the IS was working.
Is the review positive or negative?
