Copal "electric" or "electronic" battery-powered shutters

[ridax]

I've never seen a Copal 0 electronic shutter. I'm not sure they exist

I am glad to have a set of the #0 lens cells to #1 shutter adaptors made by Rodenstock. I do not use them yet but take care not to forget where I store them....

I studied electronics, so I have soft spot for electric/electronic shutters, and I collected some. I know you found the one you are searching for, but I wanted to share some pictures as reference.

This is a copal electric (size 0). it is not battery powered, but has a cable, and an internal solenoid that opens and closes the shutter.


This is the standard Compur electronic 1, I believe quite similar to your Copal electronic. I found that the Saft LS 17500 batteries are a very good replacement for the original PX-21


This is a Prontor Magnetic (size 0). I have several of those, they are quite similar to the Copal electric, but the coil of the solenoid is very different (in terms of electrical parameters).
This was part of my 8x10 (defunct?) project of making a compact wide angle camera. I even managed to score a Rodenstock Perigon 130mm for it. :-/


This is a Prontor Electric E64. This is a leaf shutter with a 64mm hole. I have also two E100 one E150 (100mm and 150mm opening respectively). The solenoids are different in all 4 shutters.

This is the shutter I have. Was hoping to locate a couple more... Will keep looking!

I had a 300mm lens for a while with a Copal electronic. Batteries were a pain to find so I wired a two cell aaa holder to the back of the lens board and ran it with that. Never had a problem with it.
