This instructive video provides a useful technique for making your very own, personalized rangefinder for the purposes of better focus accuracy with camera systems like a Rollei 35 and 35 S, Olympus XA 2, 3 and 4 as well as the LOMO LCA and Diana + camera systems… basically if you have to scale-focus your camera then this video is for you!
