Latest Canon Patent Applications (Pop-UP EVF, Resin Mount, Hybrid EVF, Lenses and Sensor)

Canon Patent Applications

Here are the latest Canon patent applications.

Canon patent application 2019-023685 describes a pop-up EVF (Electronic ViewFinder). From the patent literature:

Since a display-device part and the eyepiece for magnifying it are needed EVF, when mounting on a compact camera, the place to arrange serves as problem. Since the large-sized external display device serves as a form which covers a camera back substantially, in order to look into EVF from the back face of a camera, an external display device must be avoided and arranged. A camera will enlarge only the part of EVF then. When it is going to avoid enlargement, an external display device must be made small and usability becomes less good. In order to correspond to these problems, there are some on which pop-up type EVF like the description to a Patent document 1 is mounted. 

EVF loading is realized without [ when using this inside a camera, being stored at the time of EVF non-use, without it functions as a finder by making it jump out to camera outside and miniaturizes an external display device, and ] enlarging a camera. 

Canon patent application 2019-023688 describes a resin (plastics) made lens mount:

Conventionally, although the camera mount of the camera with interchangeable lenses comprised a metallic material in consideration of durability, reliability and accuracy, etc., the camera mount which comprises a metallic material had the problem that things and component cost with heavy weight became high. 

The camera body which has the camera mount which comprised resin materials, such as a plastic, by improvement in the durability of engineering plastics or reliability and progress of forming technique is produced commercially these days. A weight saving and component cost reduction are attained because camera mount becomes a resin material.

Canon patent application 2019-020538 describes a hybrid optical and electronic viewfinder:

The present invention relates to the single-lens reflex camera which has an optical finder and an electronic finder, and relates to the change of the finder to which seeds responded as for the electronic device with which the especially single-lens reflex camera was equipped, or the optical element. 

In recent years, the single-lens reflex camera which has a finder which has arranged the optical-path dividing prism in the optical path of an optical finder in a single-lens reflex camera, and has arranged the display device which becomes the equivalent position from a liquid crystal panel etc. optically with a focus detecting plate is known. 

Canon patent application 2019-020679 describes the optical formula for a RF 100-400mm lens (for EOS R systems):

Focal distance 102.21 195.97 389.86 ​
F number 3.83 4.93 5.85 
Half angle of view (degree) 11.95 6.30 3.18 
Image height 21.64 21.64 21.64 
Lens total length 204.85 250.29 291.30 
BF 4.31 31.68 97.49

Canon patent application 2019-017065 describes a photon counting image sensor.

Canon patent application 2019-0052781 discusses how to improve the reliability of tilt-shift lenses.

Canon Set To Use A Sony Back-Illuminated APS-C Sensor In Future Cameras?


Another weird rumor to report.

It’s suggested Canon might use the new Sony IMX571 image sensor in an upcoming APS-C camera system. No hints if it will be a MILC or a DSLR.

The Sony IMX571 sensor is back-illuminated, has a resolution of 26MP and does 16 frame per second.

Despite Canon used Sony sensors in the past for their Powershot cameras, we do not think a Sony sensor will be featured on DSLR or mirrorless camera. We did not get any suggestion pointing in this direction.

Stay tuned.

Canon EOS R and Nikon Z7 Can Not Beat Sony a7 III When It Comes To Pure Dynamic Range Sensor Figures

Canon Eos R

At Photons To Photo you can compare sensor figures of various camera.

As you can see in the image above, the Sony a7 III is still the champion of pure sensor performance, beating the Canon EOS R and Nikon Z7 on dynamic range measures.. Which is a pity especially for Nikon, since they are using a sensor made by Sony.

Canon, designing and manufacturing their own sensors. gets closer to Sony’s sensor performance as ISO gets higher (but around ISO 32000 Sony gets the edge again).

Sensor performance figures do not tell the whole story, and the differences shown in the graph above are really minimal. When it comes to ergonomics, lens ecosystem, reliability, customer support, weather sealing, and whatever counts beyond sensor performance, Canon is still the the alpha dog in the pack.
