For non-waterproof, two piece bodies Nikon has some 8x30 and 10x42 models that are some of the best that I've peeked thru, including Zeiss, Leitz, Swarovski, B&L, and such, but they're also expensive at several hundred dollars each. Better View Desired has good reviews of birding optics. For traditional 7x50 thru 10x50 binoculars Astronomy and Sky & Telescope have done nice reviews over the years, and the Nikon 7x50 ProStar and 7x50 Fujinon FMT-SX have always done well, typically being best in class. They're both waterproof, one piece body, individual focus binoculars, what most would call marine/naval models. Weenies complain about the weight as they're close to 50 ounces. The Nikons have better edge definition but the Fujinons have are threaded for a tripod adaptor, have better eye relief, mine were almost 1/2 the price, and per my eyes seem to have better color transmission. Fujinon also makes an 8x30 in the same line and the one that I looked thru also had excellent optics.
I had my Fujinon 7x50s out yesterday, just glassing the area while I was watching my kids play, and they're always a treat to look thru. I'm glad that I bought them.
