I've been playing with a Leica IIIf recently and I noticed that the focusing scale on the 35mm Summaron goes down to 1 meter but the rangefinder doesn't seem to operate at distances closer than approximately 2 meters. I removed the lens and sure enough, the part of the lens that actuates the rangefinder doesn't extend far enough into the camera body at close distances to activate the rangefinder. I have almost no experience using rangefinder cameras and I'm wondering if this is normal for a Leica? Is it normal for all rangefinders with removable lenses? Is something really out of whack with my little slice of German heaven? Greg Fraser
