I know there are a lot of factors, shutter, ISO, hand-shake, etc. but how important is Image Stabilization on a lens, say 17-40 or 10-22 range?
My original 17-85 has IS as does my new 24-105 but I keep thinking the only reason the 17-85 had it was for the longer range.
I want to go wider & bump up to FF so I have been looking at the 17-40L and wonder if I will miss the IS at that range?
Thoughts? Examples? Suggestions of other UWA (Tokina 11-16, etc.)?
