I hope it helps..... From the Leica Manual, 1951, by Morgan & Lester: ------------------------------------------------ "...Leica lenses carry an integral depth-of-field calculator, engraved on the lens barrel. "...If the left-hand figure corresponding to the lens stop in use is placed at infinity, the right- hand figure will be opposite a distance exactly half that focused upon. In this case, the figure opposite the index arrow is the _hyperfocal_distance_ for the lens aperture in question. Its value is obvious-- when a lens is focused upon the hyperfocal distance for the aperture in question, everything from half that distance to infinity will be acceptably sharp. Thus the hyperfocal distance can be considered a fixed-focus setting for outdoor [or action] shooting." -------------------------------------------------- That says it as well as anything. The oft-held idea that a rangefinder camera is not good for action shots is wrong; you just pre-focus using the above concept and forget about it.
