Unusual Canon patent describes self-lubricating DSLR body cap

We’ve shared a number of patents from Canon recently, but its latest might just take the cake for the most interesting. Canon has apparently filed a patent for a DSLR body cap that lubricates the lens mount.

Originally filed back in December of 2013, the patent breaks down the concept of a body cap that uses a porous plastic material to slightly lubricate the mount as the cap is put on and taken off.

We’re as puzzled as you are. Sure, there is a benefit in keeping the lens mount properly lubricated, such as keeping the electronic contacts clean. But, lubrication is also more likely to grab onto dust and dirt when out in the field.

We’ll file this under patents we’ll likely never see come to life. If it does, however, we’ll be sure to get our hands on one of these as soon as possible.
