Additional information from the press release:

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. 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
