You have this right. The metering area is determined by the lens attached and not be the preselector lever. All it does is show you the area that a certain lens would cover if attached. The area metered is about 1/3 of the area covered by the lens. Too bad Eastland had it wrong, that would have been really useful. Dick Hemingway Plano, TX
