View Full Version : Toyo 45GX Dof scale question

9-Feb-2007, 15:45
To use the dof scale on the rear focus knob do you,

1. focus
2. zero out the dof scale with the index mark
3. refocus so the f-stop on the scale is the same as the f-stop being used on the lens.

Am I correct or even close?

Thanks for any help.
