Canon Patent Shows a Body Cap that Cleans Lens Contacts
A simple addition could make body caps more useful
When it comes to fancy body caps, Olympus may be the winner having put an actual lens into a body cap for their micro four thirds cameras. Canon, however, has reportedly filed a patent for a body cap that actually cleans the cameras lens contacts when it’s put on.
The original page is in Japanese, but the concept seems pretty simple. A small brush tries to get the gunk off the metal contacts that help your lens talk to your camera body to enable things like autofocus.
It’s not exactly earth-shattering, but maybe if body caps also helped clean the camera, I wouldn’t lose them all the time.
