Canon EF 400mm f/4 DO IS II USM Lens 400mm option

Capture Exceptional Images with Canon EF 400mm f/4 DO IS II USM Lens

The Canon EF 400mm f/4 DO IS II USM is a super telephoto lens characterized by its relative lightweight and compact form factor. Gapless dual-layer diffractive optics are employed within this lens’ construction to produce a smaller, lighter 400mm option with enhanced correction for chromatic and spherical aberrations. Aspherical and UD elements are also used to further reduce distortions and a Sub Wavelength Coating contribute to increased clarity and contrast.

• EF-Mount Lens/Full-Frame Format
• Aperture Range: f/4 to f/32
• Gapless Dual-Layer Diffractive Optics
• One Aspherical Element, One UD Element
• Sub Wavelength Coating
• Ring-Type Ultrasonic Motor AF System
• Optical Image Stabilizer
• Power Focus, Focus Limiter, Focus Preset
• Weather-Sealed Construction
• Rounded 9-Blade Diaphragm

Complementing the sophisticated optical layout, a four stop-effective Image Stabilizer helps to minimize the appearance of camera shake and can be dedicated to different styles of shooting. Ideally positioned as a versatile option for sports and wildlife photographers, this lens’ high-performance attributes and natural handling render this a viable telephoto option for a variety of applications.

Housed within a weather-resistant barrel, this lens also features fluorine coatings on the front and rear elements for protection against fingerprints and other elements from affecting image quality. Focusing is complemented by the inclusion of AF stop buttons at the front of the lens, as well as full-time manual focus override and Power Focus mode for smooth shifting of focus.

• 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.
