Optical Elements

The Canon EF 400mm f/4 DO IS II USM Telephoto is a long telephoto lens built around the **Canon EF** mount standard. The EF mount is Canon's established DSLR lens interface, providing connectivity with a broad range of Canon camera bodies. With only mount data confirmed in the current specifications, the key verified detail for this lens is its **Canon EF** mount, which positions it within Canon's extensive DSLR ecosystem. Buyers invested in the Canon EF system will find this lens mount-compatible with their existing bodies. For full technical details including optical design, weight, dimensions, autofocus performance, and stabilization specs, prospective buyers should reach out to the seller directly or consult Canon's official product documentation to ensure this lens meets their shooting requirements.

Canon's DO lens technology uses a multi-layer diffractive optical element to reduce chromatic aberration while keeping the lens significantly shorter and lighter than conventional super-telephoto designs.

Diffractive Optics Element

A fast f/4 maximum aperture at 400mm delivers strong subject separation and supports faster shutter speeds in lower light conditions common in wildlife and sports photography.

400mm f/4 Aperture

Canon's second-generation IS system provides up to 4 stops of shake correction, with a dedicated panning mode for tracking fast-moving subjects.

Image Stabilization II

Canon's ring-type Ultrasonic Motor delivers fast, near-silent autofocus with full-time manual focus override without switching out of AF mode.

Ring-Type USM Autofocus

Compatible with the full range of Canon EF-mount DSLR bodies, including full-frame and APS-C sensors, and also adaptable to Canon RF-mount mirrorless cameras via the EF-EOS R adapter.

Canon EF Mount

The DO optical design results in a noticeably shorter and lighter lens body compared to traditional 400mm f/4 lenses, improving portability for field use.

Compact Super-Telephoto Build

Front and rear lens elements feature a fluorine coating that repels water, dust, and fingerprints, making cleaning easier in outdoor shooting conditions.

Fluorine Coating

Dust and moisture resistant sealing throughout the lens barrel makes it suitable for outdoor use in challenging environmental conditions.

Weather-Sealed Construction

A rotating tripod collar allows the lens to be mounted directly to a tripod or monopod for stable shooting at long focal lengths.

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

Such a joy to use barely heavier than a 100-400mm zoom. I did not have to bring a tripod or monopod on my birding trips. Easily handhold and carry all day. Focusing is fast, faster than any super telephoto lense in the EF system that I used. Amazing sharpness at all apertures. Comes with a L plate tripod mount, original tripod, hardcase, camo kit, hood and soft lense cover. Glass is perfect. Cosmetically in excellent shape with very little if any signs of use, always used with the camo lkit.
