I hope one of you Omega experts can help me out here.
I use Beseler enlargers in my own darkroom, but am now working at times in a darkroom with all Omega D 4x5 enlargers. I have an older Nikkor EL 150mm enlarging lens with an odd, larger than normal thread size of 53mm. I have the mounting flange.
My problem is that I cannot seem to find a lensboard (or whatever Omega enlargers require) to accept this lens. I am a bit confused about the Omega lensboard system overall. What I am working with now is a small, oblong mounting plate with a 39mm threaded cylinder that attaches via 2 thumbscrews to a larger plate on the enlarger.
I would appreciate any advice about finding and acquiring the proper set up to mount this lens on the enlarger.
Thanks in advance,
