Okay, now I finally understand what stopped down metering means ;-). This may not be irrelevant as I am going to put a screwmount lens on a Canon Elan. Not sure what the difficulties or lack or difficulties will be yet, but this may apply to me as well (since I don't *have* a *istD). Thx! Marnie aka Doe
