Featuring a unique optical design and paired with advanced image stabilization technologies, the Canon EF 400mm f/4 DO IS II USM Lens is a super telephoto lens designed for full-frame EOS DSLRs. Gapless dual-layer diffractive optics are employed within this lens' construction to produce a smaller, lighter weight 400mm option with enhanced correction for chromatic and spherical aberrations. Aspherical and UD elements are also utilized to further reduce distortions and optimized coatings contribute to increased clarity and contrast. Complementing the sophisticated optical layout, a four stop-effective Optical 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 handling 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 400mm f/4 lens is compatible with full-frame EOS DSLR cameras, as well as APS-C-sized sensors where it will provide a 35mm-equivalent focal length of 640mm.

Gapless dual-layer diffractive optics contribute to a marked reduction in chromatic and spherical aberrations as well as benefit the design of a relatively compact and lightweight lens.

One large diameter ground aspherical element and one Ultra Low Dispersion (UD) element minimize aberrations and distortions while also contributing to greater sharpness and clarity.

Optimized lens coatings help to suppress lens flare and ghosting for increased contrast and more color-neutral imagery.

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. Additionally, three dedicated image stabilization modes are available-Standard, Panning, and During Exposure Only-and can be selectively employed to suit a variety of types of shooting. Furthermore, the image stabilization system does not need to be disabled when shooting with a tripod.

An Ultrasonic Motor (USM), along with an internal focusing system, is employed to deliver fast, precise, and near-silent autofocus performance.

Located at the front of the lens, AF stop buttons allow you to intuitively stop the lens from autofocusing at any time.

A dedicated Power Focus mode produces a smooth, measured focusing movement that is well-suited to video applications.

When working in the autofocus mode, full-time manual focus override can be used to instantly switch between auto and manual focusing methods.

A weather-resistant design protects the lens from dust and moisture to enable its use in inclement conditions. Additionally, fluorine coatings have also been applied to the front and rear lens elements for further protection against fingerprints and smudging.

Nine rounded diaphragm blades contribute to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.

  • Fantastic lens
    Verified BuyerReviewed by Ararat - August 3, 2021

    It's great lens. Very sharp, fast autofocus, good Image Stabilization and top-notch build quality — all in a small, lightweight package. Best news is, you can shot from hand. I use Canon 400mm DO IS II + Extender 1.4x III and get sharp Images.

  • Great canon lens
    Verified BuyerReviewed by Nikko - July 11, 2017

    This lens is excellent and the details it captures is amazing. Not as heavy as other super telephoto lens so I can shoot handheld as well. A bit on the pricey side but well worth it.

  • Great Optics
    Verified BuyerReviewed by Lars - June 12, 2021

    The optics are five stars. Deducted one star for a design issue and two packaging issues. The design issue is not having a screw mount for a front lens protective UV filter. I don't like ever touching the lens surfaces and typically install a high-quality UV filter before I put a new lens on the camera. The other two issues I have are the included lens hood and the lens case. While both are very good quality, they are quite expensive and have drawbacks. The lens hood, installed makes the camera lens appear very large with all the white (the hood is approx. 6" X6") and will attract more attention than I care for. I also don't like the knob attachment for the lens hood. I purchased a bayonet mount black (dark gray) fiberglass/carbon fiber from Zemlin Photo for approximately 30% of what Canon charges for the lens hood. I plan to save (unused) the Canon lens hood for a backup and/or resale, but my go-to lens hood will be the Zemlin Photo hood. The Canon lens case is very nice, but expensive and large for travel. I will be looking for a quality soft-sided lens case to facilitate traveling with the lens. I would have rather saved the $1K for the included hood and case.
