David, Art, I had a similar problem and launched a topic, which prompted a long and good discussion. It might be worth reading it on http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=00BhFh To sum it up: exposure errors with manual lenses seem to be a known problem of Canon cameras. Another point is to make sure that the stopped down exposure is within the 20D's metering range. The solution: Get the DMR or live with the Leicanon limitations and frustrations.
