Mamiya 645 C lens repair

[Neil Grant]

I'm want to part-dismantle of a 150 f/4 for dust removal. Can anyone advise if the 'beauty disc' (or name plate) is a screw-in type, as on an RB lens, or a lever-out one. I'm struggling to remove it.

Thanks of you can help.

I've taken apart the 110/2.8, 80/1.9 and 80/2.8 lenses...they are all spin in beauty/trim rings on the front.

....thanks! I've seen them levered out from N lenses, glad I didn't try it.

It's a screw-out. It's been a few months since I cleaned one, but as I recall, it was fairly simple and straight-forward.
