    IS = Images Stabilizer

    The higher the magnification factor of binoculars, the more prominent is the image shaking, resulting in loss of image clarity and preventing long periods of use. Hence, all Canon binoculars are equipped with image stabilization function using technology in the development and manufacturing of camera lenses. This IS feature provides a clear, stable field of view in all scenes.

    Types of Binoculars

    There are various binoculars models available with different combinations of magnification, objective lenses, and effective diameters to fit in any situation and usage.
