New Compact and Lightweight EF Super-Telephoto Lenses Are Well Suited for a Variety of Photographers’ Needs

MELVILLE, N.Y., September 5, 2018 – Most professional photographers need to carry multiple lenses in their camera bags. Helping to lighten their load, Canon U.S.A. Inc., a leader in digital imaging solutions, introduces two new super-telephoto lenses, the EF 400mm f/2.8L IS III USM and EF 600mm f/4L IS III USM. Both lenses possess a dramatic weight reduction and high-image quality, making it ideal for shooters to easily transport and capture images during action-driven scenarios, such as sports and wildlife. Both lenses now hold the title of world’s lightest in their respective focal length*. The weight of the EF 400mm f/2.8L IS III USM and EF 600mm f/4L IS III USM lenses has been reduced by 2.2 lbs. (more than 25 percent) and 1.9 lbs. (more than 20 percent) respectively.

“When developing updates to some of Canon’s most popular legacy lenses, one common question that is asked by photographers was ‘can they be lighter,’” said Kazuto Ogawa, president and chief operating officer, Canon U.S.A., Inc. “The significant reduction of weight in these two lenses addresses this customer need and delivers thoughtfully designed, high-quality optics .”

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.

Additional noteworthy features of the lenses include:

• Upgraded Optical Image Stabilization from three-and-a-half stops to five shutter speed stops1 of correction over the previous f/2.8 lens
• Improved, flexible focus control with a customizable electronic-focus ring
• Two fluorite lenses and one super UD lens, helping to provide high image quality
• Circular nine-blade aperture
• 17 lens elements in 13 groups
• Heat-shielding paint helps prevent lens temperature from rising during excessive exposure to sun
• Fluorine coating on front and rear optical elements, helps to reduce smears and fingerprints
• Inner focusing system with Ring Ultrasonic Motor
