Case for storing film optics.

PostMon Aug 08, 2022 10:11 am

Good day forum users!

Tell me, is it possible to store cine optics in a plywood case? Here I made such a case from plywood 20 mm thick. Is it dangerous for mold to appear on the lens?

I would at least add anti moisture pads for long storage. Silica gel pads or something like that.. Peli from the famous Pelicases also have some specials for that..

Fungus grows best in dark, humid environments. A plywood case will be fine in a dry environment, but if it's humid it will likely be humid inside the case. I'm not sure how well dessicant (silica gel, etc.) would work in a case made of a porous material like wood, but they'd likely help.

Where I live, summers are short but often hot and humid; winters are long, cold, and dry. Even though summer is short it is humid enough that I lost my old film camera and its lenses to fungus; I need to get one of those humidity-controlled cases for my lenses and cameras.

I made this box to transport the lens.

The plywood looks like it’s cabinet grade. I learned the hard way that “cabinet” grade plywood is different from structural sheathing. Cabinet grade plywood is more prone to fungus especially on the edges, like the mold feeds on glue. In either event the wood should be treated to lock away the wood’s natural moisture prior to foaming.

I work with 100-200k glass housed in plywood cases regularly and most vendors are happy with black paint as a sealant. It’s not like you need to get Bob Vila with it, though it’s cooler if you do.

Good Luck
