Yes, RBT do have 0.1mm and 0.2mm pin bars. They are grey in colour so you
will not confuse them with the standard pin bars. Even when mounting well
aligned slides in RBT mounts, I occasionally find them useful to lower a
chip just that fraction of a mm to avoid a bright or contrasty stone or
similar unwanted object that is right on the base line. If my calcs are
correct 0.2mm on the film chip = 20mm (3/4 inch) of the subject at 3.5m (11
feet) from the camera.
