Canon Patents a Body Cap that Cleans the Contacts on Your Lens Mount



Here’s a cool patent that gives new purpose to a camera accessory you don’t hear talked about much: the body cap. Chances are you don’t give your camera’s body cap much thought, but the body cap Canon just patented would serve a dual purpose by not just keeping your sensor protected, but also cleaning the contacts on your lens mount in the process.


Egami spotted the patent, and it’s pretty basic. Every time you remove and re-attach the body cap, you clean the contacts on your lens mount and (hopefully) extend the camera’s usefulness for a little while longer. As with all patents it’s not necessarily something we’ll ever see in reality, but it’s a neat idea that makes an easily overlooked accessory a bit more useful.
