Stupid question.  I've read that an M lens on the *ist will only meter
wide open. If the camera can't talk to the lens, how does it know what
wide open is?  and if its reading the light coming through the lens, why
won't stopping down affect metering?  Probably an obvious answer, but I
can't see it.
