EF400mm f/2.8L IS III USM

The high image quality you would expect from a flagship lens

The use of 2 fluorite and 1 Super UD lens elements correct chromatic aberration, removing one of the last hindrances to ideal image quality on a super telephoto lens and achieving stunning visual resolution and overall contrast. The EF400mm f/2.8L IS III USM also newly features Canon’s own Air Sphere Coating (ASC) technology, which incorporates air with a lower refractive index than optical glass into the coating, forming an ultra-low refractive layer that suppresses lens flare and ghosting.

Significantly reduced weight, professional-friendly operability

5-stop IS, 2.5m closest focusing distance

Image stabilization (IS) has been significantly improved to 5 stops, with 3 versatile IS modes available, including IS Mode 2 for panning, and IS Mode 3 for unpredictable movement—created in response to popular demand from sports photographers. This, together with the drastically lighter lens body, expands the range of scenes that you can shoot by hand. A reduction in closest focusing distance to 2.5m from 2.7m on the predecessor allows you to shoot closer to your subjects while retaining same high image quality.
