EF-EOS R 0.71x

Here is a short video introducing the new Canon Mount Adapter EF-EOS R 0.71x, a speedbooster-like adpater to mount EF lenses on RF mount cameras. The Mount Adapter EF-EOS R 0.71x was announced along with the Canon EOS C70.

From Canon:

This adapter converts light transmission from full-frame to Super 35mm image format. It extends the angle of view and optical sensitivity, while seamlessly integrating with the camera’s optical corrections. mount adapter.

In addition to the flanges of the RF mount, four screws securely attach the adapter to the camera. Once mounted, the adapter maintains a similar angle of view of your full frame lenses on the Super 35mm sensor, while boosting the speed of the attached lens by an average of 1-stop. The adapter also carries all EF information through to the RF contacts, so on certain lenses, full DPAF and metadata will be available, working much as they do on a native EF mount.

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:
