Canon Patent For Box-shaped Camera Body (Cinema EOS?)

Canon Patent

Rather interesting Canon patent application. A box-shaped interchangeable lens camera.

Canon patent application 2023024538 (Japan, published 2/16/2023) discusses methods and technology for a box-shaped camera (or a protection for a box-shaped camera?).

From the patent literature:

A camera mount protection when a lens is removed from an imaging device with a detachable lens.

Description of the Related Art

A lens-exchangeable imaging apparatus is known in which a lens device can be attached to and detached from a mount formed on the front surface of a camera body. Also, interchangeable-lens imaging devices with a very short distance from the lens mount to the image sensor have appeared, such as so-called mirrorless cameras that do not have a reflecting mirror to guide the incident light of the lens device to the optical viewfinder.

Further, some interchangeable-lens imaging apparatuses have a tripod or a seat on a plurality of side surfaces of the camera body, and are capable of vertical shooting or upside-down shooting. Patent Literature 1 discloses a camera having a mounting surface and a tripod mount on the top surface. Or you can shoot with the camera fixed upside down on the gimbal.

In Patent Document 1, the lens mount protrudes from the camera body when the camera is viewed from the front side. Therefore, if the camera is placed with the mount surface facing downward while the lens device is removed from the camera body, the mount surface may be damaged.

In addition, when a large lens device is attached to the camera body, the center of gravity of the camera as a whole is shifted forward from the tipping limit, and there is a concern that the camera may topple forward. This is especially noticeable when the camera body is made smaller and lighter, such as with a mirrorless mount.


It is an object of the present invention to provide an image pickup device capable of protecting the mount of the image pickup device when the lens is removed.

Canon Celebrates 10 Year Anniversary Of Cinema EOS System

Cinema Eos

It’s 10 years since Canon introduced the Cinema EOS system. Time to celebrate.

Canon press release:

Canon’s Cinema EOS System Celebrates Tenth Anniversary

MELVILLE, NY, November 4, 2021 Canon Inc. announced today that the company is celebrating the tenth anniversary of its Cinema EOS System of professional digital cinema camera and lens products for the film and visual production industries. Since its debut, the company’s line of products has received an abundance of support from professional filmmakers around the world.

In 2011, both film-analog and digital equipment were being used side-by-side in the cinema production industry. Digitalization was continuing its spread, and digital cameras equipped with Super 35mm equivalent large-format sensors were becoming the mainstay of the industry. Amid this environment, Canon leveraged its visual technologies, including the optical technologies cultivated since its founding, and launched its Cinema EOS System, thus formally marking its entry into the cinema production industry.

When developing equipment such as cameras and lenses for the cinema production market, it’s essential to have assistance from professionals in the field who use the equipment. From the release of its first digital cinema cameras (EOS C300 / EOS C300 PL) and lenses (CN-E14.5-60mm T 2.6 L S / CN-E14.5-60mm T 2.6 L SP) in January 2012, Canon has always sought out feedback about performance, ease-of-use and recording styles from end-users on the front lines of cinema production. Canon strives to develop products with designs and intuitive ergonomics that enable the shooting styles and visual expression demanded by professionals.

Canon has continued to expand the boundaries of visual expression and pursue the development of devices with ever-evolving technology. The company’s first Cinema EOS camera, the EOS C300, which is equipped with a CMOS sensor that produces video reproduction comparable to 35mm film, was awarded a Technology and Engineering Emmy® award from The National Academy of Television Arts & Sciences (NATAS) in 2012. What’s more, the company has been honored for its cinema lenses, having received another Technology and Engineering Emmy® award in 2017 for its 4K cinema lenses that have earned high praise from the market for its excellent optical performance.

Canon’s Cinema EOS System is widely used in the modern cinema production industry, including in film and television production. The EOS C300 Mark II (released in September 2015) digital cinema camera and eight cinema lenses were used to film the 2018 Academy Award-winning documentary Free Solo. The System was also honored at the Sundance Film Festival in January 2020, where the winner of the World Cinema Documentary Special Jury Award for Cinematography, ACASĂ, MY HOME, was filmed with the EOS C300 and EOS C100 Mark II cameras (released in December 2014).
