New Product - Lens and Shutter Protectors

So let's say you want to send your shutter for repairs. The cells are fine, and there's no need to send them in. How do you store them until your shutter is returned? And how do you ship the shutter so that it arrives safely, with no damage to the diaphragm or shutter leaves?

Or maybe you have a convertible Symmar lens and want to use only the rear element for the longer focal length.
How do you keep the front cell safe until you finish shooting?

Of course, one can cut pieces of cardboard and stick them on shutters, but that's not an elegant solution. One could do the same for cells, but what to do about cells from lenses like the Grandagon 75mm f/6.8 lens? The glass protrudes from the body, and it is impossible to put anything on the glass without damaging it.

The Lens Protectors and Shutter Protectors are designed to let lens cells or shutters be stored and shipped safely. I got a small batch of Copal 0 sized Protectors made to test demand. Depending on the response, I will get them manufactured in other sizes.

The Protectors are manufactured in Japan out of POM, an engineering plastic similar to Delrin. It is very strong and does not outgas, so there is no danger with long-term storage. The hollow part in the Lens Protector is 10 mm deep, enough for almost any lens cell. The Front Shutter Protector has threads to 3mm, ensuring that it will never touch the diaphragm or shutter leaves. The Rear Shutter Protector can be threaded on even with the retaining ring attached.
