Thanks Paul, excellent review and very fair. I've changed my mind many times over the last twenty years, but now I use Canon IS (10x or 8x) almost exclusively. My 10x42 may not be optically as beautiful as my Nikon SE, but the IS feature wins hands down. If out for a casual stroll I use Canon IS 8x20 because it fits in a jacket pocket. Optically it's obviously mid-range, but again outperforms anything else in my stable (including my beloved Zeiss FL 8x32) in terms of seeing the object with stability. But other people prefer other binos, and that's grand because there's nothing like variety! And as I think someone said about 15 years ago on BF, if you go out with non-IS binos, you don't really notice its absence....you just automatically try and steady with your hands (or MOLCET) as best you can, and get on with it. One tiny, moany, petty complaint of mine is that because the IS system takes a few milliseconds to kick in, it's a little harder getting on to LBJs that are flitting about in foliage or under cover. But that's a minor quibble. Yesterday, there was an airshow in the town where we live (a pretty lousy one because the three main acts didn't show). We were up on the headland watching over the bay, and I had brought my Canon IS 10x42 and my Nikon SE 10x42. My wife hogged the Canons. 'Nuff said.
