(more than 25 percent) and 1.9 lbs. (more than 20 percent) respectively.

Canon EF 600mm f/4L IS III & EF 400mm f/2.8L IS III Lenses Announced

The new lenses are must-haves for advanced and professional photographers shooting wildlife, aviation, sports and news with Canon’s new EOS R full-frame mirrorless camera (with use of one of the three new Canon mount adapters), as well the EOS 1D and 5D series of DSLR Cameras.

Both lenses feature two of Canon’s most advanced propriety lens technologies – Air Sphere Coating (ASC) and Super Spectra Coating (SSC), helping to reduce flaring and ghosting, and suppressing the reflection of light, leading to vivid images. These updated lenses inherit the excellent overall build-quality and ruggedness photographers have come to expect and admire from the Canon EF L series of lenses. In addition, the minimum focusing distance has been improved for both lenses, from 2.7m to 2.5m (8.8ft to 8.2ft) for the EF 400mm f/2.8L IS III USM and 4.5m to 4.2m (14.8ft to 13.8ft) for the EF 600mm f/4L IS III USM.
