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 puts you right in the middle of the action with extreme intimacy. The 18x50 IS is 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.
