Canon 18x50 IS Binoculars deliver truly outstanding optical performance and a well-stabilized, high-magnification view. Whether at the water's edge enjoying a boat race or high in a stadium's uppermost deck, the 18x50 IS binoculars put you right in the middle of the action with extreme intimacy. The 18x50 IS are great for big game hunters, spectators of extremely distant sports such as surfing or extreme skiing, or anyone hunkering for incredible pulling power that can actually be enjoyed without the use of a tripod. The design is water resistant, with a tripod socket, as extended periods of observation are best enjoyed with some form of support.
The 18x50 IS were not designed to be habitually worn around the neck, but if you prefer to carry your binoculars in this manner, then consider a thick neoprene strap instead of the supplied flat woven strap. If you'll be using the binoculars in cold weather, it is highly recommended to use lithium batteries (optional) instead of alkaline.
The 18x50 IS are threaded to accept 58mm filters, which is convenient for using polarizers around water, but this also means that during extremely bright or humid conditions, you can use a pair of 58mm lens hoods to help shield the objective lenses from dew and stray light, thus improving contrast.
