Image Stabilization. Using gyro sensors and a microprocessor, these ultra-compact 10x binoculars feature built-in image stabilization that corrects for hand tremors at ±1° in all directions. To use the image stabilization system, you must install two AA batteries (not included). Runtime on a fresh set of batteries is about nine hours. Without power, the Canon 10×30 IS II functions as a standard set of binoculars without any IS compensation.

Optics. These binoculars use a Porro prism optical path for a rich depth of field that makes it easier to judge the distance between objects without eye strain, plus it enables a shorter form factor for better handling. Aberrations are corrected for distortion-free views and the wide 60º apparent field of view provides an immersive viewing experience. The 3mm exit pupil produces bright, high-contrast imagery that’s suitable for twilight.

Build. A textured, water-resistant rubber coating provides a sure grip and center-mounted focus and stabilizer controls offer great ergonomics with easy access for both hands. Please note there are no tripod mount threads on these binoculars. There are also no threads for filters. For connecting to a support system, check out the Leica Binocular Tripod Adapter. The distance between the eyepiece and your eyes is about 14.5mm, which is a comfortable amount for seeing the entire field of view without vignetting and is moderately comfortable for those in glasses. For a more comfortable set for glasses wearers with 15mm eye relief, see the Canon 15×50 IS binoculars.
