I need literature and data charts from this lens. If you could send me scans or whatever info I will be grateful. I think it has been made around the 70īs, lastest available data charts are incomplete or simply doesnīt have info about the 150.
Does this lens have all the performance of the modern longer ones? (240-300-360... in the same process 1:3-3:1 magnification) I am surprised about the mini-size of this lens.
Does anybody knows if this lens needs a spacer when mounted on a Copal 0 shutter? (... all my Apo-Ronars use spacers between the front element and the shutter... )
