![]() Thanks to Jeremy for the advice about the spring or various other metals. The Electro 35 GX is a 35mm rangefinder camera produced by Yashica of Japan in 1975. Thanks Roger and Donnie - it is good to know that the alkaline batteries are an option and that the camera will opperate with batteries of a wide range of voltages. Unfortunately I cannot play with the camera until the weekend. ![]() The advantage with the lithium battery is that it fits with minimal adjustment (it might need a shim so it is a snug fit) plus the spring to complete the circuit. ![]() I was trying to avoid the alkaline batteries because of their short life and the varying voltage the produce over their lifetime. A bit wider 40mm lens instead of the common 45mm in other Electro 35s. I eventually chose Yashica Electro 35 GL as it has a few features making this model most advanced among the entire Electro 35 series: 1. ![]() Maybe a spring from a pen will suffice (?). Electro 35’s electronic shutter operates a stepless range of speeds from 1/500 to 8 sec. I suppose I can use a spring (as Jeremy suggests) in the second battery slot to complete the circuit. The battery seems to neatly fit into one of the two battery 'slots' in the base of the camera (but curiously not into the other - I think the battery compartment has seen some wear and tear over the years). They make the point that the battery is long life and this is supported by a 2016 use by date! The lithium battery is a 'Photo Lithium' three volt Sanyo CR-1/3N. The circuit diagram from the excellent repair manual.
