    Patent: Active cooling adapter for the RF mount

    By Updated:143 Comments1 Min Read Canon Patents

    Canon News posted about a patent recently about actively cooling an RF mount camera with an adapter. In this patent, it's a cooling EF to RF adapter.

    In  Japan Patent Application 2019-186871 You can see the adapter and the flow of air from the adapter.

    Canon News says:

    The camera does have to be properly built to handle heat transfer from the sensor to the lens mount, but this is certainly something Canon could accomplish.  One of the engineering problems that even Sony and others have is how to cool a sensor that is not fixed in place because of IBIS.  Flexible heat transfer materials made of polymer do exist, so it's possible to cool the sensor directly even with IBIS.

    I recently reported that new RF mount adapters were coming, but unfortunately, this wasn't one I had been told about.

    1. Sneaky Canon had this in their sights all the time , I wonder how well it sorts the overheating issues , this could change everything . What fabulous marketing Canon , release a camera , the next day release a statement it over heats which gets everyone talking about it , including the Sony Fan boys running it down , and then hit them with this , hahahahah brilliant .
    3. An adapter is fine, but Canon should have designed this from the ground up for video.

      Canon should have made the R5 far bigger so it could handle the heat better.
      They should have included fans and a far bigger heatsink. While they were making it bigger to better handle the heat, they could have put in built in NDs to make life more convenient for the video shooter.
      Oh and with a bigger body to handle the heat better, they could have also put more buttons on the body so that you could change key video settings without having to go in to the menu i.e. dedicated buttons for ISO / shutter / FPS / peaking / zebras etc.
      With a bigger body they could have also then had full size HDMI and better audio input abilities e.g. dual XLRs and on-body control for the audio levels etc.
      With a bigger body, they could also probably have managed to come up with a solution for swapping out lens mounts easily so YouTuber bloggers could switch between EF and PL mounts for their Vlogs.
      Finally they could have had a bigger screen and also larger EVF to make working in video far easier. In fact, they probably just should have removed all the photography features and weather-sealing of the R5 because it's clearly just compromising the video side of the camera.

      If only such a camera existed in Canon's range for people that want to do video....

I should imagine there is one in the pipeline for the RF glass also , that will come out at the same time .
      I welcome this solution. I buy only one adapter and it will fix all EF lenses. At least, I don't have to buy brand new lenses. Hopefully, they will materialize this very quickly.

      Sorry but I disagree (I can't tell if your opinion is real or sarcasm). They should have done this, they should have done that. We scream too much "they should have done this". Personally, I want a small body with heating as they designed it. Someone else might have other needs. There is no way to satisfy the entire planet's need. They must decide, as a company, for a solution that they think the best. To me, additional cost, like this adapter, is the best solution. Whoever needs it, buys it. Photographers don't need it, they don't have to buy it. 8K'ers need it, let them buy it. I don't need that much 8K but I need small body for gimbal, I don't buy it. Is that too harsh as a point of view? At the end of the day, they must make compromises somewhere.
    9. Isn't this something. Canon is coming out with a camera(s) which far exceed anyone's performance expectations, and still there are folks picking at unsubstantiated nits. Tough room...

      Its sarcasm , if you want a video camera buy one , I don't need it either but its great that Canon have made it .
    14. I read today that Masaya Maeda (head of EOS) was "stepping down for health reasons". That's the Japanese way of announcing he was being replaced. And why not for the poor job he has done at the imaging division ? Substandard sensors, losing the video race, losing the mirrorless race, losing large clients like AP, losing one time enthusiasts like myself, alienating customers with misleading specs, launching faulty products like what we are seeing now.. Canon is badly in need of fresh minds.

      Definitely sarcasm. He's just describing the features of Canon's cinema line.
    19. Back at the beginning of July I guessed that one of Canon’s surprises would be a way to cool their cameras. One of the the reasons cinema cameras have robust cooling systems is that temperature effects the sensor’s ability to read color and light. If you want a sensor that 1) lasts and 2) is accurate, you need to set heat limits.

      Whether Canon introduces a way to actively cool their EOS R series of cameras through a PL mount adapter or through a battery grip, this must certainly be something on their radar.
