Canon's smallest and lightest IS Binoculars. The new IS binoculars have an appealing rounded shaped design for more comfortable handling. They owe their small size, low weight and superb image-stabilising ability to the latest in Image Stabilisation technology: the Tilt Mechanism. This mechanism keeps your subject steady by correcting movements, such as hand shake. Battery power is minimised because the IS optics only uses power when the IS button is pressed. Like the focusing knob, this button is centrally located on the binoculars, easily reachable by both left and right handed users. As a further refinement, the tilt-system Image Stabiliser of the 8x25 IS suppresses chromatic aberrations and reduces colour 'smearing' in order to keep your image clear. Being environmentally conscious Canon have used lead-free glass in the new IS binoculars.
