Canon has added two new models to its portfolio of Canon Image Stabilizer binoculars with the 10x30 IS II and 12x36 IS III. New to these binocular models is a microcomputer (similar to Canon's EF lenses) for improved IS performance and stable high-magnification viewing. The upgraded IS technology allows for greater viewing comfort, while at the same time eliminating the need for a tripod.

In addition to improving the IS performance, the latest electronic circuits were introduced, reducing power consumption over previous models. At temperatures of 25 degrees Celsius/77 degrees Fahrenheit, both new models of binoculars provide up to nine hours of continuous stabilization on a pair of AA-size alkaline batteries, compared to four hours on the previous models. Users also have the flexibility to use rechargeable NiMH batteries.

The 10x30 IS II's 10x high-magnification ratio is combined with a 30mm/1.18-inch effective diameter objective lens. Birdwatchers, specifically, will benefit from the new, less glossy front cover of this model, whose design was refined to provide a better anti-reflective surface. Additionally, their compact size and lightweight (127x150x70mm, approx. 1.3 lb.) help make them easy to carry.

The 12x36 IS III model has a 12x high magnification ratio. Its 36mm/1.42-inch effective diameter objective lens helps provide high-resolution images. These new binoculars are also compact and lightweight (5 x 6.8 x 2.7 inches [WHD], approx. 1.5 lb.) considering their higher magnification.

Both models feature Porro II Prisms which enhance image resolution and help to minimize the loss of light. Long eye relief of 14.5mm/.57-inches helps ensure viewing comfort, especially for those with glasses.

Canon?s new 10x30 IS II and 12x36 IS III binocular models are scheduled to be available in August 2015 for suggested list prices of $549.99 and $849.99 respectively.
