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