context_page_description: The EF 70–300mm lenses are a series of telephoto zoom lenses made by Canon Inc. They have a Canon EF lens mount to work with the EOS line of cameras.
  Four Canon EF telephoto zoom lenses carry the 70–300mm designation.
  EF 70–300mm f/4.5–5.6 DO IS USM
  EF 70–300mm f/4–5.6L IS USM
  EF 70–300mm f/4–5.6 IS USM
  EF 70–300mm f/4–5.6 IS II USM
  All versions offer image stabilization and ultrasonic motor drive and have nearly the same maximum aperture of 4/4.5 to 5.6 over their entire focal range.
context_section_description: 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.
