Where does the back focus begin on FSQ
Hi guys,

where exactly does the back focus begin on an FSQ106? Is it from the focusor without any adapter?

I know the Back focus for my FSQ is 178mm but I cannot seem to find much on where the back focus begins.

BTW does it matter if the focusor is racked in or out?

regards
Paul
