I have two (2) Yashica Electro 35 rangefinders for sale; the first is the model GS, the other an earlier model (not a GS or GSN). I also have the Electro 35 Lens Conversion Set, still in the original box with the leather carry case. A mercury battery adapter (see the 1st photo) is included. ou can find these on Fleabay, and they allow you to use the modern lithium 6v batteries instead of the older and toxic mercury batteries (the mercs are still available, but they are expensive). The Lens Conversion Set contains a Close-Up adapter and a Telephoto adapter. Expand the capabilities of your Electro 35 with this set! Both cameras and the lens conversion set for just $50. S/H is included to the lower 48 states.
