Michael,

thks for the very informative posting on trimming the CL's lightmeter. =
Do you have any idea how i can calibrate the meter for my R4s. The =
readings are indicating overexposure(of about 0.5 to 1 stops) on sunny =
conditions and on lower light levels its about 1-2 stops over.

Anyone has any idea what's wrong with the meter or is it norm due to the =
age and technology of the metering in this camera.
