Canonâ€™s new Hybrid Image Stabilizer (Hybrid IS) compensates for both angle camera shake and shift camera shake. It incorporates an angular velocity sensor that detects the extent of angle-based shaking, found in all previous Canon optical image stabilizer mechanisms, as well as a new acceleration sensor that determines the amount of shift-based camera shake.
The company explains that Hybrid IS also employs a newly developed algorithm that synthesizes information from the two sensors to make optimal adjustments, thereby enhancing the effects of image stabilization during shooting, including macro shooting, which had proven difficult for conventional image stabilization technologies.
Canon began researching methods to compensate for camera shake in the 1980s, and in 1995 launched the EF 75-300mm f/4-5.6 IS USM, the world’s first interchangeable SLR camera lens to feature a mechanism that compensates for optical camera shake. Since then, the company has continued to produce a variety of interchangeable lenses with image stabilization capabilities, and boasts a total of 21 such lenses in its current product lineup.
