This NEW improved design features a handle to facilitate mounting or removing the lens cap while the lens hood is in the shooting position.

The cap can be mounted on the lens while the hood is in the shooting position or in the stored position.

Don Zeck Lens Cap with lens

The lens caps are made of black material but for illustrative purposes I made a white cap which is easier to photograph.

The handle allows a firm grip on the cap so that it can be easily installed.

The handle will compress to about 3/16 of an inch for easy storage while your lens is in it's case.

These lens caps are precision machined from rugged black polypropylene and can be used with or without the factory hood.The "O" rings will not mark or damage your lens. Nothing touches your lens optics and the thick design will protect against damage to your front element.
