Canon L IS 10x42 binoculars are a high-end, luxury piece of equipment, ready for instant action in any viewing situation. An exclusive, battery-power Image Stabilizer provides clear and shake-free images, as if you had the binoculars clipped to a tripod. Waterproofing is an important boon to bird watchers and others who have reason to get out in the elements. A large lens diameter and a 4.2 mm exit pupil provide brighter and sharper images, even on dim, rainy days. Two ultra-low dispersion lens elements offer chromatic aberration correction. The unique exterior design gives you a perfect hold and grip. The Doublet Field Flattener lenses deliver crisp and noise-free viewing. The Canon 10x42 L is unusually heavy, but users often find the weight and bulk worth it for the exceptional quality.
