A rangefinder was purchased from Kiev, Ukraine. It worked fine but was a little off in the distance. Just a little adjustment to the front screw fixed that. Now one meter reads as one meter instead of 1.3. The screw was turned from 11 o’clock to 10 o’clock.
Now I can use the Zeiss Ikonta camera for closeups and for far away focusing. I’m glad I purchased this device and would do so again.
