faintnegativecharge · Feb 27, 2019

im looking for the retaining ring for this lens. Just bought it used for my Beseler 45mx.

If anyone also has a lens board for this that would be great too!

Tough to find. That's a great lens. Beseler made small extension tubes for mounting various lenses on the 3 lens turret, I am pretty sure the made a 12mm and a 21 mm tube . One end was female 50mm the other 39mm male. These would adapt your lens to a standard board. Omega made a beautiful 50mm×.75mm thread cupped board for the D series that could probably be attached to a 4x4 Beseler board. There's 50mm flanges and rings out there. Maybe someone here has one. New there 50 bucks when you can find one.

Any idea what size is required?

The Beseler HD 150/5.6 is a Rodagon. The mounting thread is 50 mm x 0.75 mm.

That's what I'm trying to figure out. To be honest, I've done tons of 35mm prints on my durst enlarger. It came with the lens board and I bought a Nikon EL 50mm 2.8 lens. I've never stepped out of the 35mm until recently when I acquired a 4x5 camera and a Hasselblad. I see tons of different extension rings, and lens boards to the point where it's making my head spin.

I should just go back to shooting Polaroid. (making a joke)

I have a retaining ring / flange in that size.
