About the Canon 15x50IS Binoculars

High-Power, Large Binoculars Perfect for Star Gazing or When You Can't Get Close Enough!

The 15 x 50 IS All Weather binoculars with one-touch Image Stabilizer technology instantly compensates for binocular shake. Large diameter 50mm front objective lenses accommodate a wide range of activities from sports to astronomical observation. A multi-coated, Ultra-low Dispersion (UD) lens element in each objective section delivers outstanding image contrast, sharpness and color clarity. To accommodate eyeglass wearers, 15mm Long-Eye Relief provides greater viewing comfort, and the ergonomic design makes holding easily. An optical anti-fog eyepiece prevents condensation and fogging in foul weather.
