The EF 70-300mm lens is a telephoto
Telephoto lens
In photography and cinematography, a telephoto lens is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a telephoto group that extends the light path to create a long-focus...

EF 70-300mm 4.5-5.6 DO IS USM

This lens makes use of Canon's Diffractive Optics rather than a traditional lens of wholly refractive design. This allows the lens to be more compact, albeit heavier and much more expensive than a lens of conventional design. The lens contains Image Stabilization

EF 70-300mm 4-5.6L IS USM

Introduced on August 26, 2010, this lens is designed to provide professional photographers the 70-300mm zoom range without sacrificing high image quality. The 70-300mm f/4-5.6L IS USM is the only L-series 70-300mm lens and is the only to feature weather sealing. The image stabilizer is rated for 4-stops of image stabilization and allows sharp pictures to be taken handheld at speeds as slow as 1/8 of a second. This lens has superb contrast that meets or exceeds other L-series telephoto zooms, but lacks in sharpness in the corners throughout most of the focal length range. The image quality at 300mm does not degrade, making it distinct from the other 70-300mm lenses. Barrel distortion is average for this class of lens, but vignetting is better than average. Because of its fast autofocus, useful range, excellent image stabilization, and high image quality, the 70-300mm f/4-5.6L has recently become popular among serious amateur and professional photographers. The 70-300mm f/4-5.6L includes a hood but does not include a tripod ring.
