I have been completely satisfied with my Swarovski 8.5x42EL binoculars. I prefer the 8.5x to the 10x model generally, they are easier to use quickly, less fussy with alignment to your eyes, easier with glasses/sunglasses on, and less tiring than higher magnification when using for long periods of time. Leicas I've tried were just as good. Zeiss has some very good models, but I did not experience the "wow" factor of best image quality with the ones I tried. Smaller objective lenses are a compromise, more portable but not as easy to actually use and poorer low light performance. Meopta and Steiner may be worth a look and are more economical. Your eyes may be different.
