This is the problem. Once the metering values generated by the camera were affected by the viewfinder light leakage, the final exposure would be improper. If say, metering through the lens produced 1/125 @ f/8 with blocked finder, uncovering the eyepiece would produce, say, 1/200 @f/8 (we are working in Av mode) which is about half stop underexposure. During the exposure, even though the finder leakage will be blocked by the mirror in it's raised position, the actual exposure values will be 1/200 @ f/8 (those the camera determined just prior the mirror is flapping up).

Yes, light entering the viewfinder COULD affect metering by the camera, but that same light WON'T reach the film/sensor surface. tomp ----- Original Message ----- From: "Alex Zabrovsky" <[EMAIL PROTECTED]> To: "EOS list" <[EMAIL PROTECTED]> Sent: Saturday, October 19, 2002 1:31 PM Subject: FW: EOS3 viewfinder and eyepiece shutter > This is exactly what I meant.
