Canon's lightweight 400mm f/4 — DO II with diffractive optics reducing weight by 30% vs conventional.

The Canon EF 400mm f/4 DO IS II USM was released in 2014 as the second-generation diffractive optics 400mm telephoto prime for Canon EF-mount. Eighteen elements in 12 groups including gapless dual-layer diffractive optics and UD elements. Nine rounded aperture blades. 52mm drop-in filter slot (no front filter thread). At 2,100g. 3.3m MFD. IS rated 4 stops.

Eighteen elements in 12 groups (gapless dual-layer DO + UD + aspherical elements). Nine rounded aperture blades. 52mm drop-in filter slot — no front filter thread. At 2,100g. Minimum focus distance of 3.3m. Ring USM for fast AF. IS rated 4 stops. f/4 maximum aperture. Full-frame coverage. Canon EF mount.

The DO (Diffractive Optics) element is the defining technology: gapless dual-layer diffraction grating elements bend light using diffraction rather than refraction, allowing fewer conventional elements for equivalent telephoto correction and reducing overall length and weight versus conventional 400mm f/4 primes. The DO II adds a second gapless diffractive layer over the original DO version, reducing the colour fringing that single-layer DO designs could produce.

On the used market the Canon EF 400mm f/4 DO IS II USM is available at Canon L telephoto prime pricing. Condition checks: ring USM AF response, IS operation, 52mm drop-in filter slot. Note: no front filter thread — 52mm drop-in only. Compatible with Canon EOS EF bodies; on RF via EF-RF adapter.
