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. Ihre Kamera arbeitet nicht mehr einwandfrei, Ihr Objektiv bringt nicht mehr. Barrel distortion is average for this class of lens, but vignetting is better than average. The image quality at 300mm does not degrade, making it distinct from the other 70–300mm lenses. This lens has superb contrast that meets or exceeds other L-series telephoto zooms, but lacks in sharpness in the corners throughout most of its focal length range.

It is designed to provide professional photographers the 70–300mm zoom range without sacrificing high image quality. The lens includes 19 elements in 14 groups, two of which are ultra-low dispersion (UD) glass. Introduced on 26 August 2010, this lens is in Canon's L-series range of professional lenses. This lens is compatible with the Canon ET-65B lens hood. That is an uncommon attribute of consumer grade zoom lenses and is not the case for the old 75–300mm lens.

This is because it features an ultra-low dispersion glass element, something that is uncommon for a consumer grade lens, and is usually found only in Canon's L-series lenses.
