I just received a new camera body, 3D Printed, and the helicoid for my 65mm lens has a Hyperfocal scale marked on it.
The marking are on only one side of the scale( which is in meters).
The f16 mark is at 3 meters. I’ve been told that with the helicoid set at 3 meters everything from infinity to 2 meters will be in focus.
I am used to a DOF scale which has f stop marking on either side of the lens showing near and far focus points at a particular focus point.
That hyperfocal distance marking seems to be based on very conservative enlargement. If you scan your film at high resolution you will find that it is not sharp at infinity.
Hyperfocal is always a matter of what is defined as „acceptably sharp“ and that depends on how much you magnify the image (and/or at what distance you view it).
I would suggest using a DOF calculator e.g PhotoPills but be more conservative with your format - don’t pick 6x17 but rather 6x6 or even 35mm. This would mean hyperfocal at about 5m or 9m respectively.

I probably will not use it. I’ll be using a lazer to determine focus point. I was just curious about this as it was new to me.
I have a bunch of cameras which have the hyperfocal mark. It is basically a set it and forget it thing for outside sunny snapshots where the user just wants to take pics and is not concerned about ultimate quality.
I have found it works best for the 8-20ft distance range.
