Originally posted by AlwaysAl As a wearer of bifocals, the diopter adjustment has been a god-send.
Recently, at a show, the Pentax representative indicated the proper way to set the diopter adjustment was to remove the lense look towards a light source and adjust the slide until the focus lines appeared clear in the viewfinder. The implication was the actual numerical strength of the adjustment was secondary to gaining comfortable functionality.
Previous to this "lesson" had always checked/set the diopter with the lense on and auto-focused on a detailed subject. Since adopting this new process, I find the images a little clearer and I can shoot without glasses on.
