hey bill,
i don't know yet.
i have yet to win the auction but if i do win, my plan was to just guesstimate using the 100 mm framelines as my guide and hope like heck it's doable.
to be honest, i've never had to use a seperate viewfinder and with no experience at all, i have pre judged the experience as awful, so i was not thinking about using a finder.
it will be a while before the transaction is complete and i have the lens in my hot little hands and i don't want to hold you up, so for now i'll say a gracious thank you and pass - and hope like hell you still have one later on if i change my stubborn mind.
ironicly enough, the 100 mm lens comes with a finder
