My question is this: RE Bolex RX H16
If you want to mount your camera on a tripod or other device and you want it to pan around the optical axis you will find that the mounting holes on the flat base are NOT on this axis.
This may not be anykind of issue for people but for me its a disaster. So what is the measurement from the ‘line’ that the 5/8 and 1/4 holes makes (RED LINE) to the optical axis (GREEN LINE)? Does anyone know? Yes, just measure it you say. Well, where are you measuring to, by sight, to the middle of a marked safety cap maybe, to the centre of a marked safety filter maybe, etc. Surely this information is known by Bolex?
Anyway, I’ll measure it for myself and publish it here….
