Still, they are equipped with an integrated tripod mount for use with any standard photographic tripod. That's just in case you don't feel like holding onto your binoculars all the time. High-performance features include: Extra-large field of view with crystal clarity from edge to edge; Ultra-smooth center focus that's easy to operate, allowing you to pinpoint your subject, Right diopter adjustment so you can fine-tune your viewing. Most impressive, though, is the sheer size of the 20x80 SuperGiants. The 80mm objective lens diameter is huge. In fact, you won't find many larger, and definitely not in the Zhumell's price range. Once you try these big binos for astronomical or terrestrial viewing, you won't want to go back to anything smaller. And, given all the Zhumell's advantages, there's simply no reason you'd have to. --jtyl
