I have for sale a rather unusual Copal CVS Electronic Shutter Control System. While this is a used system, it is in very good operating condition.
This system was originally made for Toyo View Cameras, but can be used on any camera that will accept Copal 0, 1 and 3 size shutters.
I am including three Copal CVS-10 shutters, meaning that they are actually Copal 1 size, but with factory-installed adapters for Copal 0 lens elements, and two Copal CVS-1 shutters (Copal 1 size).
The system consists of the following:
1. Copal CVS Control Unit
2. Battery Pack
3. Charger
4. Grip / Release
5. Three nos. Copal CVS-10 0 size shutters and retaining rings
6. Two nos. Copal CVS-1 1 size shutters and retaining rings
7. Power cord from the Battery Pack to the Control Unit
8. Shutter Cord from Control Unit to Shutter
9. Release Cord from Grip/Release to Control Unit
An AC adapter was made for it, but I do not have it. The battery pack is a simple 12V, 3A, 500mAh unit. The charger is built for 100V, but a transformer can be used if necessary. It would be easy, and perhaps better, for a competent person to adapt a newer battery pack with much higher capacity. Paramount (for cords), and Quantum (for batteries) may be able to help.
Speeds are available from 1/250th second (for 0 size shutters) and 1/125th second (for 1 and 3 size shutters) to 16 seconds and B. Focusing may be done at fully open aperture or taking aperture. Since the shutters I have are all actually size 1 shutters, speeds are from 1/125th only.
Apertures are set on the Control Unit through a system of magnetic tabs. Each shutter/lens is supposed to have its own tab. I have one blank tab that can be used as a template for making your own tabs. I will explain this procedure to the buyer. It is very simple, and can be done easily. Otherwise, a camera repair person like SK Grimes can easily make these tabs.
An X-sync flash port is available on the Control Unit. Since I do not know the voltage generated by the Control Unit, I recommend using a Wein SafeSync or similar device to ensure the safety of your equipment.
I have a photo-copied Japanese language manual. Additionally, I will provide a basic English how-to guide.
This is a relatively inexpensive way to get automated control of shutter speeds and apertures for photographers using digital backs with view cameras.
I am asking USD 2700 for the complete system, including free worldwide tracked and insured shipping via JapanPost EMS. Payment is through Paypal or wire transfer.
