• Superb Image Quality
• 17 Elements in 13 Groups
• Fast Auto Focusing (AF)
• 52mm Drop-in Filter Size
• Built-in Tripod Collar

Next-generation super telephoto L-series lens with an Image Stabilizer, it’s one of the world’s best lenses for wildlife and nature photography. The optical system is newly designed with a maximum aperture of f/4. One fluorite element and two UD-glass elements effectively correct aberrations resulting in sharp and excellent delineation.

Canon’s EF 500mm f/4L IS (Image Stabilizer) USM Lens provides AF with any EOS body even when used with the EF 1.4x Extender. Weather-resistant construction, excellent durability, superb AF speed and optical quality combine with Canon’s Image Stabilization for incredible imaging potential. This lens weighs 8.53 lb (3.87 kg) so a tripod or monopod is a required accessory. A tripod collar is built into the body of the lens.

• Fluorite & UD elements eliminate secondary spectrum chromatic aberration
• Full-time manual focus override
• AF Stop function shuts off autofocus when an obstruction appears
• Dust & moisture resistance made exceptional by magnesium alloy lens barrel and new rear gasket at lens mount
• Two-stage image stabilization; dual-axis camera shake correction or vertical axis only (for panning)
• 3-stage focus limiter
• Focus preset function allows for returning to a specifically set focus by turning a ring in front of the focus ring

The Canon EF 500mm f/4.0 L IS USM Lens is simply a super lens.
