Which Lee 77mm adaptor ring for RZ67 (?)

The three Mamiya lenses for my RZ67 are; 50mm/110mm/180mm which all accept a 77mm filter thread.

Question is (?);

I have the Lee 100mm filter system, do I only need the standard 77mm adaptor ring, or; the 77mm wide angle adaptor ring for my RZ lenses ?



Thanks in advance.

77mm wide angle adaptor

I suggest the wide. I have the wide on my RB setup. If you're using wide angle lenses, 50 & 65, there is a chance of getting vignetting at times especially if you start to stack filters at all. I also use my same filter system on my 4x5 lenses with adapter rings. Even with the Lee Wide Adapter I've had vignetting. I can't say exact circumstances it has happened, but without the wide ring I'm sure I'd see more of it.
