I was reading the "Leica Compendium" by Jonathan Eastland and I came across this: "...the photographer can accurately measure very small areas of the object to be photographed using the preselector lever." He goes on to state, "By flicking the preselector lever to bring up the 90mm bright-line frame, particular areas of the scene can be measured and interpolated. Even smaller areas an be metered using the 135mm projected frame, in effect giving the photographer a selective metering facility." Am I to assume then if I have my 35mm lens on the camera and I want more of a "spot-meter" reading, I can simply flick the bright-line frame selector to the 90mm frame and the metered areas gets correspondingly smaller? How can this be? I thought the metered area was determined by the lens attached, mechanically. If the above is true, how would the camera know how much area to meter since the bright-line frames are shared by two focal lengths (the 90mm and the 28mm share the same bright-lines)? Confused in Sacramento and it's only 7am. Mike Rivera >> Enormous mistake . The frame selector does nothing else than bringing another set of frames in the VIEWFINDER . The mesuring surface is a fixed area ( WHITE SPOT ) , whose value NEVER vary . Since you bring different frames corresponding to your lenses , you have to " Guessimate " the area of the mesuring spot ( ABOUT THE THIRD OF THE HEIGHT OF THE FRAME . How can someone make such an error when studying a camera and writing a book about it ????? Chears JO GOODTIMES -FRANCE/ AIRBORNE RADAR TECH / LIVE FREE OR DIE
