Canonet Ql17 DOF scale

I made a spreadsheet hyperfocal table for Contax G, which also has a 45mm lens, that I could print very small and tape to the back of the camera

Discarding the rows for lenses other than 45mm should leave you with the right values.
That's different from a leica-style dof scale on the QL lens itself, but it might be a start, and the formulae are already in the spreadsheet. cheers!
