Product Research


Overview: The Canon EF 70-300mm f/4-5.6 IS II USM lens is a telephoto zoom lens for Canon EOS cameras. This EF lens is recommended for use on full frame cameras, but can be used on cameras with APS-C or APS-H image sensors. It covers a wide range of focal lengths, and is recommended for sports and nature photography. The lens features a built-in Image Stabilizer (IS), as well as an Ultrasonic Motor (USM). The new Lens Information Display shows the focusing distance, focal length, and the amount of camera shake.

Image Stabilizer (IS): The built-in Image Stabilizer can be used in the AF (autofocus) or MF (manual focus) modes. The Image Stabilizer gives the equivalent effect of a shutter speed up to four stops faster. The Image Stabilizer provides more reliable handheld photography and clearer detail in low-light situations.

Nano USM: The EF 70-300mm lens is equipped with Canon's Nano USM technology. The built-in Ultrasonic Motor (USM) gives you high-speed autofocusing for still images, and a Stepping Motor (STM) for smooth, silent autofocus for movies. No motor noise is picked up by the camera's microphone as the focus changes.

Focusing Ring: Regardless of whether you're in manual or auto focus mode, the focusing ring always works. This means you can auto focus on a subject, but manually change the focus by turning the focusing ring.

Zoom Ring Lock: As you zoom in, the lens extends up to approximately 2-1/2" inches in length. A zoom ring lock helps prevent the lens from extending on its own when carrying the camera on a strap.

Optional Accessories: Optional accessories for the EF 70-300mm lens include:

  • ET-74B Lens Hood: The lens hood attaches to the end of the lens to block stray light from entering the lens, and prevents flare and ghosting.
  • LP1222 Lens Case: The lens case protects the lens when it's not in use.
  • Lens Filters: The lens has a 67mm filter diameter for screw-on lens filters.
