Hi, I would like to ask you if the following formula I found online is reliable for calculating extreme close up magnification With a bellows:

New Magnification = nM
Original Magnification of Lens = M
Total Extension = T (in mm)
Focal Length of Lens = F (in mm)

nM = M + T/F

Thank you very much.

That works with extension tubes as long as I take into account an adapter I need to bring a non-oem lens to infinity to start.
