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 2.1kg. 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.

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 2.1kg. 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 flareFLAREOccurs when a point light source such as the sun or an artificial light (that is brighter than the rest of the scene), hits the front element of a lens resulting in a lack of contrast, haze, or unwanted semi-transparent objects being present in the image. You can avoid lens flare with a lenshood or filters, however, the effect is also useful for bringing artistic elements into an image, such as sun rays peaking out from behind a rock formation. 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 Stabilisation technology

Shoot confidently using shutter speedSHUTTER SPEEDAperture, shutter speed and ISO form what is known as the exposure triangle in photography. Shutter speed is the length of time that a single frame is exposed for, more specifically how fast the shutter opens and closes to permit light entering the lens, to reach the sensor. A slow shutter speed means a longer exposure time useful for motion blur like the silky look of flowing water, whereas a fast shutter speed means a shorter exposure time useful for freezing the appearance of motion in images like a hummingbird in flight. It is measured in seconds starting at 1 second and halving our doubling in time. For example: 1/2s, 1/4s and 1/8s are all fractions of a second with 1/2s being the longest exposure time, 1/4s half of that and 1/8s another half etc.s up to four stops slower than normal. The EF 400mm f/4 DO IS II USM’s Image Stabiliser (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.
