This was made for a Canon AT-1 but should work
with any camera that uses the 6V battery
size PX25, A544, 4L44
Cameras with electronic shutters run down batteries
quickly when the shutter is left open for a long time.
The 6V battery is replaced by 4 AA rechargeable batteries.
The adapter comes with 4 rechargeable batteries
and a charger.
I made this to take long film exposures, but now have
CCD camera so I do not use it any more.
Will sell for $20.00 shipped.
Continental USA only.
Payment can be Paypal or money order.
