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

Canon Patent Application: IBIS and Lens IS Working Together

Canon Patent
View Post

Here is another Canon patent application dealing with how to make IBIS (In Body Image Stabilisation) and lens IS work together smoothly.

Canon patent application 2019-215426 (Japan) discusses the possibility of a change in the composition that occurs when IBIS and lens IS are working together. If both are working only while shooting, the resulting composition might be slightly shifted compared to what was seen in the viewfinder.

Although the camera in the image on top resembles more a DSLR than a MILC, we think this patent application too will find its way in a future EOS R camera body. We expect two new EOS R cameras in Q1 and Q2 2020, will this technology be already on board?

We have no doubts that Canon will feature IBIS 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.
