The Canon EOS R System Might Be Used To Produce VR Footage, Patent Suggests

Canon Eos R

Is Canon planning some VR (Virtual Reality) production system based on the Canon EOS R camera system? A patent application appears to suggest exactly this.

Canon patent application 2020-42197A (Japan) discusses optical formulas for a dual view anamorphic optic for 35mm full-frame mirrorless cameras (i.e. the Canon EOS R system).

  • Focal length: vertical 7.44 mm, horizontal 5,57 mm
  • F number: 4.00, 2.81
  • Half angle of view: 90, 90
  • Image height: 11,75 mm, 8.75 mm
  • Lens length: 100.00 mm
  • Back focus: 15.92 mm

Intriguing, isn’t it? What plans does Canon have with the EOS R system and the RF mount? At least it has become very clear that Canon is very committed to their new full frame mirrorless system.

Canon Patent: Battery Grip That Works With Different Cameras

Canon Patent

Well that’s an interesting Canon patent application. One that might get into production.

Canon patent application 20200073213 (USA) describes a battery grip with adapter that fits various cameras.

From the abstract:

An accessory attachable to an image pickup apparatus through an adapter includes a body portion configured to contact the adapter, a screw engageable with a screw hole in the image pickup apparatus through a through-hole formed in the adapter, an operation unit configured to move the screw relative to the body portion. The screw is movable in a plurality of directions including a direction along an optical axis of the image pickup apparatus and a direction orthogonal to the optical axis in accordance with an operation of the operation unit by a user.

From the patent literature:

SUMMARY OF THE INVENTION

[0004] The present invention provides an accessory and camera system, each of which is generally attachable to a plurality of types of camera bodies.

[0005] An accessory according to one aspect of the present invention attachable to an image pickup apparatus through an adapter includes a body portion configured to contact the adapter, a screw engageable with a screw hole in the image pickup apparatus through a through-hole formed in the adapter, an operation unit configured to move the screw relative to the body portion. The screw is movable in a plurality of directions including a direction along an optical axis of the image pickup apparatus and a direction orthogonal to the optical axis in accordance with an operation of the operation unit by a user. A camera system including an image pickup apparatus, and the above accessory also constitutes another aspect of the present invention.

[0006] An accessory according to another aspect of the present invention attachable between a battery grip and an image pickup apparatus includes a body portion configured to contact the image pickup apparatus, and a first positioning member configured to position relative to the image pickup apparatus. The body portion has a through-hole into which a screw of a battery grip is inserted in order to fix the battery grip to the image pickup apparatus.

Canon Patent: 13-21mm f/2.8 Lens For EOS R Camera System

Canon Patent

Here is another Canon patent application dealing with a lens for the Canon EOS R full frame mirrorless system.

Canon patent application P2020-30251A (Japan) discusses optical formulas for a 13-21mm f/2.8 lens for a full frame mirrorless camera system, i.e. for the EOS R system.

  • Zoom ratio: 1.58
  • Focal length: 13.40 17.30 21.20 mm  
  • F number: 2.88 2.88 2.88
  • Half angle of view: 58.23 51.35 45.58  
  • Image height: 21.64 21.64 21.64 mm  
  • Lens length: 150.15 136.89 130.04 mm
  • Back focus: 20.96 25.13 29.31 mm

This might well be a lens that goes into production, sooner or later.

The Optical Viewfinder Is Not Dead, Canon Patent Suggests

Canon Patent

This Canon patent suggests that despite all the mirrorless hype, and even now that Canon announced the development of a new industry game changer, the EOS R5, there is sill need for an OVF (Optical ViewFinder).

Canon patent application 2020-27113A (Japan, spotted by Hi Lows Note) shows that a big company like Canon is still doing R&D on optical viewfinder implementations.
