I'm in the market for a pair of binoculars and have just about settled on Steiner 8x30 Wildlife pros. However, I just discovered that companies are now making image stabilizing binoculars with internal gyroscopes to help take shaking images out of the equation. From the reviews on sites like amazon of the Canon models they seem pretty revolutionary. My only concern is durability. Does anyone use IS binos? Can they stand up to field conditions?
