Do you just set the camera up on a tripod and focus on objects at various distances while recording the lens position, or is there another way to do it more easily?
This is exactly how I've always done scales with homemade cameras. I have a rangefinder that I trust...I pick a few distances that I want on my scale, use the rangefinder to find things that are at those distances, then focus the camera to get the scale for the camera. There may be a quicker way, but I doubt there's an easier one.

Best of luck.
