Mamiya Sekor Lens

[SoulfulRecover]

A couple years ago when I bought my Mamiya RZ67 it came with a second lens that's for the RB67. I have heard that you can use this lens with the RZ however the light meter wont work. Is this true? Also does anyone know if this is a decent lens? I have not used it and was considering selling it but I would like a little more information on the lens before I sell it then regret it.

its the Mamiya Sekor SF C 150mm f/4
