I have an older model 135mm Componon-S for enlarging but I'm missing the retaining ring. I measured 49mm for the threads but according to Schneider's in German, I managed to figure out the proper retaining ring would be the M50 x 0.75 ring. Does this sound right? If so, there is NOTHING available anywhere except for Schneider's ring which costs $50.00........ that's more than what I payed for the lens
Yes, they want 50 dollars for an ounce of aluminum... I'm strongly hoping that I'm wrong here.
Here's Schneider's documentation: http://www.schneiderkreuznach.com/ar...componon_s.pdf
