This affordable and lightweight Canon EF 100-300mm f/4.5-5.6 USM zoom telephoto lens differs from the 75-300mm models with its higher-performance ring-type Ultrasonic focusing motor and superior AF speed. It also uses rear group focusing - so the front elements never rotate during focusing - and adds fulltime manual focusing capability. It's excellent not just for outdoor sports, but any subjects requiring the versatility of a telephoto zoom.
