There's much to like about it, but since rangefinder cameras don't provide TTL focusing, there's no way to be sure that a new body or lens focuses accurately short of shooting pictures of yardsticks, etc. What I am looking for is a rangefinder accuracy tester that an owner or prospective purchaser can use to verify rangefinder calibration. It should be simple in concept: a metal body cap with precise cams (in up to four positions) that will simulate the effect of a lens focused at various distances (infinity, 1 meter, 20 inches, ???). Once a body is known to have an accurate rangefinder, it can then be used to check whether the focusing cam on a given lens provides accurate distance information. Anyone seen anything like this? Or do I have to cobble it together myself? Thanks in advance for any suggestions. - -- Pieter Bras pieter@world.std.com
