Hyperfocal scale

[Shaps]

Have not run into this before. New camera with helicoid marked in meters. Has Hyperfocal scale that I do not understand. Can you help me?

The scale simply shows the Near distance 'in focus' at each aperture setting.

If you focus to the "32" mark and set your aperture to f/32, the range of acceptable focus will be from infinity to an unspecified close distance (smaller than the set distance).

What size film- 6x9? 6x12?

Here's a hyperfocal calculator page- https://www.studiojpic.com/calculators/hyperfocal-distance-calculator/

Looks to me that your tick marks are pretty close for 6x12 on this calculator.

Assuming that the lens is at infiinity when when set to the tick mark above the meter scale, I would say that you align the mark for y our aperture at this same tick mark and get focus from infinity to a place closer than the tick mark. And that this point, the close focus point on the scale, is what is missing?

The marks are just what you set to get the largest focus range for a given aperture. They are the thin lines.The fat lines are corresponding to the numerical focus markings in meters. Maybe you want to make them a different color for readability. Cool camera.
