I've been given an opportunity to consider purchasing a Bolex RX4 with Vario Switar 86EE (18mm-86mm f/2.5) Zoom Lens. I'm being allowed to consider the purchase by testing the camera first, since the seller is local . (this is from someone selling their husband's equipment , but she knows nothing how it works. )
I've used a Bolex before , but never with the Kern Vario Switar 86 EE (18mm-86mm f/2.5) Zoom Lens. It's the zoom lens that is puzzling me.
I've ordered some film to run through the camera (which looks and sounds like it's in good shape) , but I'm puzzled by the Vario Switar 86EE (18mm-86mm f/2.5) Zoom Lens. From what I can read about it this has an EE meter powered by one PX13 1.35v battery , the modern equivalent of which is Wein Cell MBR625 1.35v zinc air battery.
I've already put a fresh Wein Cell MBR625 1.35v battery into the chamber of the Vario Switar 86EE (18mm-86mm f/2.5) Zoom Lens, but I can't tell if it is working or not. Is there any way to test if the battery is working ? If I set the ASA and the film running speed (24fps) with the longer , small barrel under the lens should I be seeing some change in the viewfinder when I move the camera from a light to a dark area ? I don't see any moving needle with f stop indications in the viewfinder. How do I know if it is working ?
If the EE automatic diaphragm control with a cadmium sulphide photo resistor is DEAD can I just use an external meter and set the f stop manually on the Vario Switar 86EE (18mm-86mm f/2.5) Zoom Lens ?
Does anyone know where I could download the manual for the Vario Switar 86EE (18mm-86mm f/2.5) Zoom Lens ?
