Canon working on weather sealed lens adapter, patent application suggests

Canon Patent

A few days ago we learned how well the EOS 5D Mark IV can cope with water. It’s just natural we found a Canon patent application for what appears to be a weather sealed lens adapter (EF/EF-S to EF-M, is my guess).

Canon patent application EP20170178735 describes a lens adapter which is protected against dust, water, whatever.

The present invention provides a technique that ensures reliability of an electric connection between a lens adapter and an apparatus body with a simple configuration even when a spacer is inserted between the lens adapter that has an electrical communication unit and the apparatus body of an image pickup apparatus. Moreover, the present invention provides a technique that ensures a dustproof performance between the lens adapter and the apparatus body of the mage pickup apparatus even when the lens adapter has the electrical communication unit.

According to the present invention, the reliability of the electric connection between the lens adapter and the apparatus body is ensured with the simple configuration even when the spacer is inserted between the lens adapter that has the electrical communication unit and the apparatus body of the image pickup apparatus. Moreover, according to the present invention, the dustproof performance between the lens adapter and the apparatus body of the mage pickup apparatus is ensured even when the lens adapter has the electrical communication unit.

I’d love to know what exactly this lens adapter is for. Is it the next iteration of the already existing EF/EF-S to EF-M adapter (), or has it something to do with Canon’s upcoming full frame mirrorless camera which is rumored since a while? Any help is welcome, patent literature is difficult to read.

canon patentPatent applications filed by a company do not necessarily mean the described technology will hit the market any time soon. Patents are a way companies have to protect their intellectual property and research. Some Canon patent applications that in our opinion might indeed go into production are these:

Techart unveils the Canon EF lens to Fujifilm GFX 50S adapter with Autofocus & Aperture control

Guangzhou China, Sep 20, 2017 – The innovative adapter developer, Techart, who has previously launched the first autofocus adapter for manual lenses, has unveiled the world’s first Autofocus adapter for Canon EF lenses & Fujifilm GFX 50S camera. The Techart EF-GFX adapter provides autofocus function as well as in-body aperture control for using Canon /Sigma EF-mount lenses on the Fujifilm GFX body.

Techart has tested extensively on the modern Canon / Sigma EF-mount lenses in the market and found the autofocus performance on the GFX is satisfactory. Aperture of the lenses can also be adjusted on the camera by simply turning the command dial. The EF- GFX adapter currently supports AF-S mode for shooting and supports the lens Image Stabilization function (if applicable). Focal length and aperture data will also be saved into the adapter.

Techart is also working to unlock the AF-C and video-shooting feature. It is expected to be seen in future firmware release. The firmware of the adapter is user-upgradable and can be done by simply plugging the adapter into a computer via the Micro USB cable and running the update program.

The short flange distance of Fujifilm GFX 50S provides a perfect platform for adapting different mount lenses. Although not every one of the full frame EF-mount lenses has a big enough image circle to cover the GFX sensor, Techart EF-GFX adapter still opens up a wide range of lenses options for GFX users to consider.
Pricing and Availability

The Techart Canon EF – Fujifilm GFX Autofocus Adapter is currently available for pre- order at our official website ( The recommended retail price is USD 499/pc. Free shipping will be provided during the promotion period. Delivery will commence from mid Oct onwards. 1-year warranty is included.
