In Reply to: Crown top rangefinder-cam or infinity stops wrong? posted by Lawrence Ober on January 10, 2001 at 16:13:38:: I just purchased a top-rangefinder Crown (made 5/67)
: and the rangefinder does not appear to be focusing
: accurately. It is equipped with a 135mm Xenar. The
: cam is #31. The cam list on this site indicates a #6
: for the 135mm and the #31 for 132mm. If I focus on an
: object 8 ft. away the scale reads about 13 ft., etc.
: My assumption is:
: 1) The cam is incorrect.
: 2) The infinity stops are set incorrectly.
: 3) It needs internal adjustent.
: Where do I start?
Maybe I've missed the obvious. When I rack the track all the way
back the focusing scale reads beyond infinity. Perhaps, all I need
do is adjust the scales for infinity? I have no way yet to verify
anything on a real image until I at least pick up a Polaroid
back.
