My M3 has the marks you >are all talking about, but how do you use them? The upper - wider - notch shows the Depth of Field at f16 for a 50mm lens. The lower, much narrower notch, shows the DOF at f5.6 for a 50mm lens. This means that if the split image of an object in the viewfinder does not exceed the width of the upper notch that the object is then considered within the depth of field at f16. I haven't studied the question in decades, but believe that this should hold true for other focal length lenses. Anyone know? John Servais Bellingham, Wa
