I recently acquired a Ricoh 500 triggermatic rangefinder camera and will be posting my experiences with it here soon. These seem to be well built cameras – mine is from 1958 or so and still functions properly. Fits nicely in the hand and has lever arms on the focus throw and a fast film winding lever that unfolds at the base.
For now this post will be a holding page for the research I’m doing on it as well.
