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

EF 70-300mm F/4-5.6 IS USM

This lens is of a conventional design and was introduced in 2005, to offer an increase in performance from the earlier 75-300mm lenses in the Canon EF lens lineup. Like the 70-300mm f/4.5-5.6 DO it contains an image stabilizer; however, for focusing it uses the lower quality micro-USM design, and therefore requires the focus motor to be disengaged before manual focusing. The optical performance of this lens is competitive to Canon's L series telephoto zoom lenses, such as the 70-200mm series of lenses. 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. This lens is also notable for having only a slight decrease in performance as the focal length goes beyond 200 mm. That is an uncommon attribute of consumer grade zoom lenses and is not the case for the old 75-300mm lens.

This lens is compatible with the Canon ET-65B lens hood.
