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
- 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.
