-) I thought the attachment was the "Spot" one (with electrical contact), not the "Tele"-attachment as shown
-) I mixed up the Luna Pro F with the Luna Pro (US designations are different from the rest of the world)
The Luna Pro F has NO contacts thus any correction for an attachment must be set manually.
The corrective factor is 1 stop at 15° and 3 resp 2 at 7.5° with incident- resp. flash-light
5 stops deviation though would be off for the "Tele"-attachment
