I finally got my very first rangefinder off ebay. Yashica G Electro 35. I received it today and I have few questions. Battery - What kind of battery does it take? Does it take one of those older mercury batteries? Is there a way to get them? or alternative? Focusing - I noticed that when event I put the focus ring on infinity, I couldn't quite focus to the object that was very far away. Is this normal? or is there a problem that can be fixed? Thank you for your time, your help is greatly appreciated.
