Canon EF 70-300mm f/4-5.6 IS USM Lens

The Canon EF 70-300mm f/4-5.6 IS USM Lens is a relatively light telephoto zoom offering a broad range of focal lengths from a single optic, with good optical quality and excellent autofocus performance from its USM motor. It has a circular aperture diaphragm to help create natural out-of-focus highlights, and its built-in image stabilizer allows you to handhold the lens at shutter speeds 3 steps slower than would otherwise be possible, making it very practical for capturing still subjects in quite low light. The stabilizer can be activated to only correct shake in the vertical axis for panning action when desired as well.

The lens' AF is very quick, and it features a zoom lock button that keeps the lens safe and secure when not in use or when being used at the shortest 70mm focal length setting. The EF 70-300mm f/4-5.6 has Canon's "Super Spectra" lens coatings for ideal flare-resistance, and is ideal for travel, sports, and general photographic applications.
