Recommended Accessories for your Purchase

Canon EF 400mm f/4 DO IS II USM is a high-performance super-telephoto lens that uses a Diffractive Optics technology that corrects the undesirable optical effects. Its f/4 aperture combined with 52mm Drop in filter diameter helps to get enough light passing through the lens so you can still capture images or movies in dim conditions. You can choose to facilitate Ring USM AF and Full Time Manual Focus depending on your preferred imaging. The 4-stop Image Stabilizer guards you against camera shake and maintain its sharpness. Thanks to the weather sealed construction, your lens is protected from dust and moisture. Ultra Sonic Motor provides silent yet fast autofocusing to get your best angle and view in an instant.

Product Features in Detail

Portable, lightweight design

The EF 400mm f/4 DO IS II USM is smaller and lighter than a conventionally designed 400mm f/4 lens, weighing in at just 2100g. This is made possible by using Canon’s innovative Diffractive Optics (DO) technology, which corrects for the undesirable optical effects that would otherwise come about through such a drastic reduction in size.

Improved resistance to flare and fringing

The third-generation DO technology used in the EF 400mm f/4 DO IS II USM makes it a superb performer, particularly in the hands of those shooting sports, wildlife and news photography. The lens is resistant to flare and coloured fringing, and delivers excellent sharpness right across the frame.

Image Stabilizer technology

Shoot confidently using shutter speeds up to four stops slower than normal. The EF 400mm f/4 DO IS II USM’s Image Stabilizer (IS) will guard against camera shake and preserve critical sharpness. The lens’ IS operates in one of three modes: the first is for still subjects, the second for panning shots, while the third is designed for erratic, fast-moving action.

Staying focused

Intuitive controls on the barrel of the EF 400mm f/4 DO IS II USM fall instinctively under the fingers when you’re shooting. Use the wide manual focus ring to make fine adjustments without taking the camera away from your eye. Focus Preset and Focus Stop controls allow photographers to concentrate on a specific point in the scene.

Great for movies too

Power Focus technology lets photographers shooting video produce pull-focus type effects that transition smoothly between different parts of the scene.

Built to perform

When conditions get tough, the EF 400mm f/4 DO IS II USM lets you keep shooting with confidence. Weather sealed construction guards against dust and moisture, while anti-smear fluorine coating on the lens’ front element repels water and dirt.
