Let me start out with a disclaimer. I've never used rangefinder, the closest I've come is a Nikonos III (which is a viewfinder). So I really don't know how rangefinders are SUPPOSED to work, so I'm having a bit of trouble figuring out how this one works. I am tinkering around with a Zorki-4. Everything seems to be in good practical order except I am having a bit of trouble figuring out the shutter dial. I am told Zorki-4 needs to be cocked before I set shutter speed, but once I cock the shutter, the shutter speed indicator moves out of place so I can't point it to the speed I want directly. Can anyone point out what I am doing wrong? The indicator seems to be pointing at the current speed when the shutter is not cocked. Also, what is under the shutter speed setting? I have a dial with an arrow then number increasing by 5 from 0 to 25. Is this the flash delay setting?
