Capture the Action with Canon EF 400mm f/2.8L IS III USM Lens

The EF 400mm f/2.8L IS III USM is a Canon L-series optic well-suited for outdoor, wildlife, and sports applications. This version III of this prized lens features a lighter weight design along with a sophisticated optical layout and updated handling capabilities. The fast maximum aperture enables extensive control over depth of field for isolating subjects using selective focus, and it also benefits working in difficult lighting conditions.

Both Super UD and fluorite elements are used in the optical design to help reduce color fringing and chromatic aberrations for high clarity and color accuracy, and Super Spectra and Air Sphere Coatings have been applied to individual elements to suppress flare and ghosting for increased contrast and color neutrality when working in backlit conditions.

• EF-Mount Lens/Full-Frame Format
• Aperture Range: f/2.8 to f/32
• Super UD and Fluorite Elements
• Super Spectra and Air Sphere Coatings
• Ring-Type Ultrasonic Motor AF System
• Customizable Electronic Focusing Ring
• Optical Image Stabilizer
• Weather-Sealed Design, Fluorine Coating
• Detachable, Rotatable Tripod Collar
• Rounded 9-Blade Diaphragm

Beyond the optical attributes, this 400mm f/2.8 is also characterized by its advanced five stop-effective Image Stabilizer system, which has three separate stabilization modes to suit various shooting applications. Also complementing handling is a sophisticated ring-type USM, which provides quick, quiet, and accurate autofocus performance along with full-time manual focus override.

A customizable electronic focusing ring further contributes to precise manual focus control, by affording three focusing sensitivity levels for different applications. Additionally, this lens is weather-sealed for use in trying environmental conditions, and it has a removable rotating tripod collar to benefit working atop a tripod or monopod.

• Super telephoto prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 1280mm equivalent focal length.
• Relatively bright f/5.6 maximum aperture affords control over depth of field for isolating subjects and producing selective focus imagery.
• Two fluorite elements, along with one Super Ultra-Low Dispersion element and one ultra-low dispersion element, are used to greatly reduce color fringing and chromatic aberrations in order to achieve greater clarity and color accuracy.
• Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.
• An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four shutter speed stops to better enable working in low-light conditions and with slower shutter speeds. In addition to the single-shot standard IS mode, a second mode is also available that it optimized for panning.
• A ring-type Ultrasonic Motor (USM), along with an internal focusing system, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
• A Focus Preset function is available to quickly recall a programmed focusing position.
• Focus Limiter switch lets you constrain the focusing to three different ranges to suit different applications: 19.7-65.6′, 19.7′-infinity, or 65.6′-infinity.
• Rounded eight-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
• As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions.
• Fixed rotating tripod collar benefits working with the lens atop a tripod or monopod.
• Compatible with optional EF 1.4X and EF 2X teleconverters.
