Hello!
I recently acquired a Nikkor M 300mm f9 and want to know the 'range' of focus on an Ebony 45S (with appropriate extended lensboard).
The 45S extends 270mm while the lens has a backflange of 290mm. I intend to use a 35mm top hat/extended lensboard so this will give me 15mm to play with. However, while the lens will focus at infinity with the top hat I don't know what the minimum focusing distance would be. I don't want to buy the lensboard and waste my money if the minimum focusing distance is still miles away so would anyone know what the minimum focusing distance would be?
Many thanks.
:-)
