Upgrading to this lens has proved versatile, coping with landscapes successfully when required. Focussing is incredibly fast and image quality is outstanding. It works incredibly well with 1.4x and 2x Extenders with some reduction in focussing speed.  For use with fast moving subjects, it works well with the camera in “Manual” mode, with shutter speed set to 800 (or faster as necessary) with aperture set around F10 and ISO set to ”Auto”. This is a favourite lens for wildlife photography and videography used it mainly with a full-frame camera. Use on a cropped sensor camera you get even better reach!

Versatile super-telephoto performance

The EF 100-400MM F/4.5-5.6L IS 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 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 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 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 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.
