Canon Patent: Imaging Sensor Protection Mechanism

Canon Patent
View Post

Here is an interesting Canon patent: a mechanism to protect the sensor from dust and dirt while no lens is attached.

Canon patent application P2021-103248A discusses a technology able to protect the imaging sensor of a camera from dust and dirt when no lens is mounted (e.g. while changing lens). From the patent literature:

PROBLEM TO BE SOLVED: To provide an image pickup apparatus with a barrier mechanism capable of being arranged in a small space while avoiding interference with components other than the barrier mechanism.

When the interchangeable lens is removed from the interchangeable lens type image pickup device (camera), dust may enter the camera through the opening of the mount and adhere to the image pickup element. Therefore, the image pickup device may be equipped with a barrier mechanism that protects the image pickup element by closing the opening of the mount. Patent Document 1 discloses a barrier mechanism configured such that a barrier closes an opening of a mount when the lens is not attached and the barrier is opened by rotation when the lens is attached.

As asobinet.com rightfully notices, the patent is not for a “compact shutter unit”, as wrongfully stated by some sites:

Some overseas information sites misrepresent it as a “compact shutter unit”, but it is just a shutter mechanism for “sensor protection” and a technology to prevent dust from adhering to the sensor when changing lenses. is. The compact sensor barrier seems to be a space-saving design that suppresses interference with other parts.

Kevin Raposo compares the Canon EOS R5 vs EOS R6. A very detailed breakdown of more than 20 aspects that differentiate the two cameras. Enjoy.

I have the impression the EOS R6 flies a bit under the radar and doesn’t get the attention it deserves. There are many features that the R6 shares with the EOS R5, a class leading autofocus system for instance, and the R6 has an imaging sensor derived not less than from the flagship EOS-1D X Mark III.

Canon Announces Service Center For Pro Photographers At Tokyo 2020

Olympics Tokyo 2020
View Post

Canon pulled their booths from the Olympics but does (obviously) support professional photographers and their equipment at the Olympic Games Tokyo 2020.

Canon press release:

Canon establishes professional photographer Photo service center inside the Tokyo 2020 Main Press Center

TOKYO, July 19, 2021—Canon Inc. and Canon Marketing Japan Inc. announced today that the company will establish a photo service center for professional photographers in the Main Press Center (MPC), where members of the international press gather, during the Olympic and Paralympic Games Tokyo 2020 (henceforth, Tokyo 2020 Games) with the purpose of ensuring photographers are as best-equipped as possible to capture exciting and definitive moments of top-class athletes.

Professional photographers around the world require camera manufacturers to develop state-of-the-art technologies and top-class-performance equipment, as well as provide a comprehensive network of meticulous service and support.

Thus far, Canon has provided on-site support for press photographers, including camera and lens maintenance and technological support, behind the scenes at major sporting events around the world. The Tokyo 2020 Games are no exception—there too, Canon will apply its professional support know-how acquired over its long history in order to provide flexible and appropriate support for photographers and the various requests and equipment troubles they may have.

The Tokyo 2020 Games Main Press Center, located in the West Hall of the Tokyo Big Sight convention center, is expected to receive many members of the international press. As a Gold Partner of the Tokyo 2020 Games (still cameras and desktop printers), Canon aims to contribute to the successful operation of the event. With this goal in mind, the company will establish the largest camera photo service center of this event within the MPC.

At the photo service center, which will operate under the motto of “Zero Downtime” to ensure that photographers don’t miss their chance at capturing decisive moments of this intense competition due to equipment trouble or other such problems, Canon will provide speedy maintenance service, equipment repairs and loaning of replacement equipment so that photographers can always be ready and in the best possible condition.

The Canon photo service center will provide such equipment as the company’s professional flagship camera, the EOS-1D X Mark III, as well as the EOS R5 and EOS R6 mirrorless cameras and super-telephoto lenses. In addition, elite and highly trained staff will be working on-site to support photographers until the end of the closing ceremonies of the Tokyo 2020 Games.

In addition, Canon’s remote camera system will be used at the event venues. The Robotic Camera System CR-S700R enables digital interchangeable-lens cameras (DILC) to be operated remotely, including the ability to adjust shooting angles, and can be installed and used in locations at the event areas where human photographers cannot access, such as from ceilings.

Canon strives to support photographers aiming to capture historic and powerful moments of top-class athletes engaged in fierce competition and contribute to the promotion and development of photographic culture. In addition, the company will support the efforts of the media to deliver to people around the world moments of passion and excitement during the sporting world’s premiere event, thus contributing to the promotion of the Olympic and Paralympic movement.
