Abstract
The Canon EF 75-300 mm IS USM lens is the world's first interchangeable lens equipped with an image stabilizer. The production of this lens entailed the development of technologies to resolve the problems inherent to SLR cameras, including measures for ensuring optical performance even during image stabilization, for obtaining a wider range for image stabilization, and for normal photography without the image stabilizer turned on. A direct-drive image stabilizer mechanism and an image stabilizer locking mechanism with two actuators have been developed.
