Canon Patent For A Lens Cap That Might Be Pretty Difficult To Lose

Canon Patent

Canon patent application 2019-113645 describes a design for a lens cap that might once for all solve the issue with lost lens caps.

The lens cap described in the Canon patent opens (and closes) without being removed form the lens. There is more: the lens cap is a lens cap when closed and becomes a lens hood when opened. Pretty smart.

The present invention works as a lens hood function at the time of shooting and as a lens protection function at the time of non-shooting, thus eliminating the need for lens cap attachment / removal and barrier opening / closing operations.

More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production are these:
