Canon Patent: 10-20mm f/4, 9-18mm f/4, And 11-22mm f/4 For RF mount

Canon patent

A new Canon patent, and as almost all Canon patents of the last two or three years it is for RF mount lenses.

Canon patent 2023005851 (Japan, published 1/18/2023) discusses optical formulas for three wide angle lenses for the RF mount:

  • 10-20mm f/4
  • 9-18mm f/4
  • 11-22mm f/4

The 11-22mm in the list above could well be the already rumored 11-22mm lens. From the patent literature:

An object of the present invention is to realize a negative lead zoom lens that is compact and has a wide angle of view and yet has high optical performance in a wide zoom range.

Example 1

  • Focal length: 10.30-19.40
  • F-value: 4.12
  • Half angle of view: 62.03-48.12
  • Image height: 19.40-21.64
  • Overall length: 129.14-132.69
  • Back focus: 15.09

Example 2

  • Focal length: 9.27-17.46
  • F-value: 4.12
  • Half angle of view: 64.34-51.10
  • Image height: 19.30-21.64
  • Total length: 124.52-125.00
  • Back focus: 15.37

Example 3

  • Focal length: 11.33-23.28
  • F-value: 4.12
  • Half angle of view: 59.58-42.90
  • Image height: 19.30-21.64
  • Total length: 130.00-131.90
  • Back focus: 16.34

Canon Set To Soon Announce A Super Telephoto Lens For The RF Mount?

telephoto

It seems Canon might soon announce a super telephoto lens for the RF mount, i.e. for the EOS R camera system.

Rumor has it that Canon might be set to announce a new super telephoto lens for the EOS R mirrorless system- But which one it might be no one knows.

Speculation suggest Canon might release RF mount versions of the popular EF 200-400mm f/4L IS 1.4x and the EF 500mm f/4L IS USM II lenses. Both are professional lenses with professional price tags.

No more intel for the time being. Stay tuned for more…

Photography Blog posted their exhaustive Canon EOS R6 Mark II review. From their conclusion:

The new Canon EOS R6 II is a solid rather than spectacular upgrade of the 2-year-old original R6., but considering that the 2020 model was already so good, that’s certainly no bad thing.

Canon have sensibly chosen to refine, rather than revolutionize, what was already a very capable camera, principally improving its burst shooting capabilities and auto-focus system along with incorporating 20% more resolution, more capable video and improved connectivity.

[…]

The R6 continues to be a much more affordable proposition that still delivers almost everything that an enthusiast photographer or videographer could possibly want, buoyed by the addition of the new sensor, 40fps burst shooting, more versatile auto-focusing and unlimited video recording.

Overall, the new R6 Mark II is a sensible evolution of a an already great camera, adding enough new features and extra performance to keep it both competitive and still worthy of our highest 5-star Essential award.

Wildlife Photography With Canon EOS R6 and EF 500mm f/4

canon eos r6 manual

Neat video about how to do wildlife photography with the Canon EOS R6 and the Canon EF 500mm f/4 (through adapter).

Paul Miguel Photography posted a 12 minutes video about how he uses the Canon EOS R6 and the Canon EF 500mm f/4 for wildlife photography. Rather interesting because he combines a relatively new camera with a relatively old lens, which was also built for another mount type (albeit still a Canon mount). He says:

Wildlife Photography with the Canon R6 and Canon EF 500mm f/5 […] lens. I’m testing out the Eye Autofocus (Animal Eye) for this combo on beautiful Red Squirrels in Yorkshire. How well does my old Canon EF lens work with the Canon R6.. and does the Eye Autofocus Tracking Mode really work?
