Now wouldn't it be possible to correct this error when you want to shoot with a stopped down K or M lens on the *ist? Suppose I want to use a lens with the widest aperture of 3.5 stopped down to 6.7. According to what you said, the shot would be underexposed by two stops. But if I tell the camera to overexpose by two stops, wouldn't this lead to a correct exposure?? Does this make sense or am I missing something? Stefan -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ Bitte lächeln! Fotogalerie online mit GMX ohne eigene Homepage!
