I have just purchased a 180mm lens for an RB 67. Will this lens work on a RB 67 Pro S body.
I thought you could, but did a quick web search just incase and here is someone else talking about the RB67 lenses on a RZ67 body.
Yes. The only problem comes up on the RB 67 ProSD, where you have to have a special ring/spacer around the rear element to prevent light leaks.
