This is the 2nd IS Canon binoculars I've purchased. They deliver a good close-up of far away items, but need some changes. Firstly, the eye cups, if not rolled down, severely limit the field of vision to a very narrow range.

The exit pupil is a little smaller than the older version, but it doesnt make a noticeable difference. The optics are outstanding and the new IS is superb. The standard IS is fine most of the time.
