As well as expanding their EOS R camera and RF mount lens lineups, Canon still seems to be going pretty hard on the long telephoto lenses for the EF mount. Canon News has discovered a number of US patents alluding to what appears to be the recently released 400mm f/2.8L IS III USM, which stole all of Sony’s “Lightweight” thunder, as well as new 300mm f/2.8, 500mm f/4, and 800mm f/5.6 telephoto lenses.

While no specific product names have been mentioned, the two patents, #US20190041605 and #US20190041606 list several lens specifications.

300mm f/2.8

  • Focal length: 294.00
  • F-number: 2.91
  • Half angle of view (degrees): 4.21
  • Image height: 21.64
  • Total lens length: 276.40
  • BF: 65.35

400mm f/2.8

This is possibly the already-existing 400mm f/2.8L IS III USM, or this is a lens that’s way down the line. Given that the Mark III hasnt’ been out all that long, it’s extremely unlikely that Canon would be looking to replace it so quickly.

  • Focal length: 392.00
  • F-number: 2.90
  • Half angle of view (degrees): 3.16
  • Image height: 21.64
  • Total lens length: 371.25
  • BF: 69.92

500mm f/4

  • Focal length: 490.00
  • F-number: 4.12
  • Half angle of view (degrees): 2.53
  • Image height: 21.64
  • Total lens length: 410.77
  • BF: 66.03

800mm f/5.6

  • Focal length: 784.00
  • F-number: 5.80
  • Half angle of view (degrees): 1.58
  • Image height: 21.64
  • Total lens length: 484.53
  • BF: 75.94

As always, these are just patents. There are no guarantees of new lenses, although some of these are due for a refresh. Given the interest in Canon’s 400mm f/2.8L IS III USM and 600mm f/4L IS III USM, Canon may be looking to complete their lightweight telephoto lineup.

    Which lens at present can fit Canon EOS m100 as super zoom telephoto ?

      Get an EF-EOS M adapter and any EF telephoto lens can be used with the M100. Viltrox makes one for around $50, less if you know how to shop around.
