Recommended Accessories for your Purchase

The Canon EF 100-400mm f/4.5-5.6L IS II USM is a long ranging telephoto camera lens that encompasses f/4.5-5.6 Aperture Range and 100-400mm Focal Length. It is capable of a fast AF thanks to the Ring-Type USM AF Motor with Internal Focus for optimized AF algorithms and Rotating Zoom Ring with Torque Adjustment to enable easier zoom tension setting in cases of personalized control. The lens construction is of one fluorite and one super UD element and is treated with Air Sphere and Fluorine Lens Coatings to reduce aberrations and distortions and as well to reduce lens flare and ghosting. A four-stop effective Optical Image Stabilizer with 3 Modes helps minimize camera shake and image blur resulting to a more defined and sophisticated imagery. EF 100-400mm also features rounded 9-Blade Diaphragm, a detachable, rotatable tripod collar, and weather-sealed design. It belongs to the EF Mount L-Series Lens and is compatible with APS-C and Full Frame Sensor DSLR Cameras

Product Features in Detail

Versatile super-telephoto performance

The EF 100-400MM F/4.5-5.6L IS II USM is ideal for photographers who are travelling light and want to take just one telephoto lens with them. A great choice for sports and wildlife photography – the 100-400mm zoom range puts you right next to distant subjects, and lets you react quickly in a fast-changing situation. When used on cameras featuring APS-C sized sensors, the EF 100-400MM F/4.5-5.6L IS II USM offers angles of view equivalent to a 160-640mm on a full-frame camera.

Stay sharp, whatever the light

The EF 100-400MM F/4.5-5.6L IS II USM delivers sharp, high-contrast images, using Fluorite and Super Ultra-low Dispersion (Super UD) lens elements to tackle artefacts and distortion. A three-mode Image Stabilizer guards against blur from camera shake, allowing handheld shooting with shutter speeds up to 4 stops slower than normal.

Fear no flare

Shoot into the light confident that Canon’s multi-layered Air Sphere Coating (ASC) will protect against flare, ghosting and reduced contrast. ASC uses a multi-layer coating to reduce reflections including a layer of nanosized air spheres deposited on the lens surface to slow down light more gradually as it enters the lens, this prevents the internal reflections that reduce image quality. 

Ergonomic handling

Different photographers work in different ways. Use the Zoom Touch Adjustment ring to set the amount of resistance felt when zooming the lens: a light touch is ideal when you’ll be working quickly in a fast-changing situation. On the other hand, you might want to stiffen or lock the zoom mechanism when you don’t want the focal length to change accidentally.

Fast focus when you want it

Enjoy fast USM autofocus that locks on accurately and in near-silence. Full-time manual focus override allows precise adjustment without taking your camera away from your eye. The EF 100-400MM F/4.5-5.6L IS II USM focuses down to 0.98m, letting you react to subjects that come unexpectedly close.

Protected from the great outdoors

Keep shooting even in tough weather conditions. As an L-series lens, the EF 100-400MM F/4.5-5.6L IS II USM is sealed against dust and moisture, so you can keep shooting even when conditions turn bad. A fluorine coating on the lens’ front element repels dirt making the lens easy to clean.
