Technical query really.
I'm about to archive a whole series of 35mm transparencies and 6x6 negatives. I am planning of making use of my Phase 645DF, P40+ & 80mm lens coupled to a copy stand.
My question is which Extension Tube would be most applicable for this type of work. I cannot find anywhere that details focus distances, magnifications etc.
Also would the 80mm with extension be appropriate for this job?
Many thanks for your help!
