The Canon EF 75-300mm f/4-5.6 IS USM is a telephoto zoom lens for 35 mm SLR Canon EF cameras. The lens was announced in September 1995 and is the world's first interchangeable lens for SLR cameras equipped with an image stabilizer.
The image stabilizer offers a 2-stop shutter speed advantage. The lens is equipped with an AF micro-motor. The front element and the focus ring rotate with the filter during autofocus operations. Compatible hood ET-64II.
In October 2005 the lens was replaced for the EF 70-300mm f/4.0-5.6 IS USM with a seemingly similar, but yet different 15/10 optical scheme (with one UD element). That variant features an extended range of focal lengths and enhanced image stabilizer.
