A few years back, I looked at a lot of glass, and decided on the Kahles 8x32 binoculars. They are almost as bright as most 8x40's, and a lot smaller and easier to carry. I hunt in the East. Out West, you might want a 10x glass. For use in heavy, dark woods, you might want maximum light transmission with a 40mm or bigger objective lens. The quality of the glass and its coatings have a lot to do with what you see, how you see it, and what you pay. Personally, I think the Kahles are a step above most, close to the Zeiss / Swarovski standard without the high price.
