Elmar does good light

A few days ago I scored an old Leica MR-4 lightmeter for the M3. It seems to perform well, as the reading is right on par with the built-in meter on my Leica MP and my handheld Gossen Luna LUX. The MR-4 couples mechanically to the shutter speed dial on the M3, so what I essentially have now is a aperture-priority camera.
