Mounting a Rodenstock Rodagon 150 mm f5.6 on a Omega D ProLab II enlarger?

[Oscar Carlsson]

I'm still trying to assemble a kit for enlarging 4x5" negatives, and I've recently bought a Rodenstock Rodagon 150 mm for this use. I have an negative holder for 4x5" (and several for 9x12 cm...) on it's way, but yesterday I discovered that I can't mount my 150 mm on any of my current lens holders.

What do I need to mount it properly? I think I'm simply missing the lens plate, but what plate is needed?

Apart from that, my enlarger has a variable condenser (for 150 mm I simply remove the top condensor), I'll have a 4x5" negative holder pretty soon, and afaik I should have everything I need to finally work with large format negatives.

OK, so 3 minutes after posting this I found the following reference:

You need the 421-933 plate for 50 mm diameter lens.
