Canon Patent: RF 17-70mm Lens For EOS R Camera System

Might this Canon patent application lead to a product that will actually hit the shelves? We’ve not made up our mind so far.

Canon patent application 2020-012922 (Japan) discusses optical formulas of what might become a future kit lens for the Canon EOS R full frame mirrorless system. The patent literature discusses formulas for two 17-70mm and a 16-60mm lens, and for both the EF and the RF mount. We think the RF mount lens is the one to have an eye on. The discussed lenses:

Canon EF mount:

  • Focal length 17.40 35.00 68.00  
  • F-number 3.33 4.09 5.88  
  • Half-field angle (degree) 51.19 31.72 17.65  
  • Image height 21.64 21.64 21.64  
  • Total lens length 168.42 153.33 168.42  
  • BF 38.32 53.44 84.11  
  • Focal length 16.30 35.00 60.00  
  • F-number 3.31 4.22 5.88  
  • Half angle of view (degrees) 53.01 31.72 19.83  
  • Image height 21.64 21.64 21.64  
  • Total lens length 68.46 153.33 168.42  
  • BF 38.35 56.15 83.82 

Canon RF mount:

  • Focal length 17.40 34.99 67.97  
  • F-number 3.31 4.12 5.88  
  • Half angle of view (degrees) 51.20 31.73 17.66  
  • Image height 21.64 21.64 21.64  
  • Total lens length 168.41 154.99 168.39  
  • BF 8.36 52.48 81.91

Canon Patent: IBIS Might Come To The Canon EOS M and PowerShot Lineup Too

Canon Patent
View Post

We have no doubts that Canon will feature IBIS (In Body Image Stabilisation) on future cameras, given the remarkable collection of patent applications dealing with it and the fact that a Canon exec told the world about. And it’s very likely that the first Canon camera to feature it will be mirrorless.

Never the less, Canon patent application 2019-219650 (Japan) discusses how to feature IBIS on what seem to clearly be cameras in the Canon EOS M and Canon PowerShot lineup. So, IBIS coming to the m ore entry level oriented Canon cameras? Maybe not soon, but maybe sometime.

And yet another Canon patent application for yet another RF lens.

Canon patent application discusses the optical formula for an RF 135mm f/1.4L USM for the Canon EOS R full frame mirrorless system.

  • Focal length: 131.00mm
  • F-Number: 1.41
  • Half angle of view: 9.38°
  • Image height: 21.64mm
  • Total lens length:  182.28mm
  • BF: 13.87mm

We think this Canon patent application has a good chance to hit the market. In other words: we might see such a lens sooner or later.

Canon Patent: RF 24-100mm f/2.8 & RF 24-85mm f/2.8 Lenses For The EOS R System

Here is very interesting Canon patent application (2020-8773A, Japan) for two zoom lenses for the EOS R full frame mirrorless camera system. Might be a patent application that hits the market sooner or later.

The lenses described in the patent application appear to be for the RF lens mount, i.e. for the Canon EOS. Optical formulas for an RF 24-100mm f/2.8 and an RF 24-85mm f/2.8 lens are discussed in the patent application.

Embodiment 1: 24-85mm f/2.8

  • Focal length: 24.70 50.00 85.00 mm
  • F number; 2.90 2.90 2.90
  • Half angle of view: 41.22 23.40 14.28
  • Image height: 21.64 21.64 21.64 mm
  • Lens length; 153.30 173.51 198.31 mm
  • Back focus: 12.00 26.12 43.44 mm

Embodiment 2: 24-100mm f/2.8

  • Focal length: 24.70 50.00 101.85 mm
  • F number: 2.91 2.91 2.91
  • Half angle of view: 41.22 23.40 11.99
  • Image height: 21.64 21.64 21.64 mm
  • Lens length: 158.52 176.33 218.42 mm
  • Back focus: 10.00 26.38 43.15 mm

Canon Patent: Mirrorless Cam With Very Large Display And Virtual Control Wheel

Canon Patent Application
View Post

Here is a Canon patent application (2020-005214, Japan) dealing with a mirrorless camera having a pretty large display on the back.

According to the patent literature, the large display on the back should replace the control wheel you usually find on the back of a Canon camera. As you can see in the image above, a virtual control wheel is displayed (should also have haptic feedback). Moreover, it seems more than one virtual control wheel can be displayed on the display and that there is sort of visual feedback in the electronic viewfinder.

This is pretty cool in our opinion, and definitely might get into production.

Canon Patent Application For RF 24-300mm f/4-5.6 Lens

Canon Patent Application
View Post

Canon is working on consumer oriented lenses for the EOS R system, and this Canon patent application seems to confirm the commitment. An upcoming RF lens just leaked through a certification authority.

Canon patent application P2019-219679A (Japan) discusses the optical formula for an RF 24-300mm f/4-5.6 lens. We think it is an RF mount lens since the patent literature refers to a full frame mirrorless camera.

  • Zoom ratio: 11.77
  • Focal length: 24.72 90.83 290.86 mm
  • F number: 4.12 5.00 5.88
  • Half angle of view: 41.19 13.40 4.25
  • Image height: 21.64 21.64 21.64 mm
  • Lens length: 165.57 210.57 255.57 mm
