Unusual lens - need some help please
I have aquired a Shneider Componon-S 5.6/100, nothing unusual in that I guess but it black metal with a range of 5.6 to 45, no clicks or display window. And here's the best bit, the thread is 32mm and very fine pitched! I have been using the lens on my enlarger with bluetack and the images seem pretty sharp but I need an adapter or something for it so I can swap between lenses.
Anyone know what this lens might have been used for and if I can get an adapter ring for it?
