Film Sheaths and Adapters for Plate Holders

[B.S.Kumar]

----------------POSTED WITH MODERATOR APPROVAL--------------------

Thanks to Jason, we've seen renewed interest in glass plates and plate holders. Most plate holders can also use film with appropriate sheaths. I sold a number of sheaths and adapters, and have had inquiries for more of them.

Perhaps there is a demand?

I'm talking to a machine shop about 4x5 film sheaths and the adapters to use them in Japanese style halfplate bookform holders. They will be made out of 0.5mm aluminum and black anodized. They look like this:







Ideally, the 4x5 sheaths should also fit other plate holders.

Outer dimensions are:

Sheath: 100 x 125 mm
Adapter: 119 x 164 mm

I'd be grateful if some of you can give me measurements (in millimeters, if possible) of your sheaths and adapters.

Pricing is likely to be:

4x5 Sheath - 1,800 JPY each
Halfplate > 4x5 Sheath Adapter - 2,700 JPY each
Shipping will be additional via e-Packet or EMS, depending on order value.

Before starting production, I'd like to determine which film sheath sizes might be popular. I'd be grateful if those of you who are interested could take the poll. The manufacturer is okay with small quantities of 25 in each size, so even if your format is an odd size, chances are that it can be made.

Note that the sizes given are for the film. The adapter frame shown is for Japanese half-plate bookform holders, and can be modified for the size you have. Some holders may not need the frames. Generally, frames will not be needed when the plate and film sizes are the same. For example, a Half Plate film holder will not need a frame for a half plate film sheath, but will need one for a 4x5 or smaller sheath.

Please share your thoughts in this thread or via email.

Kind Regards,
