This sale is for a really mint condition (and looks unused) Mamiya RB67/ RZ67 bellows lens hood G-3 for most of the Mamiya RB67 / RZ67 standard and telephoto lenses using a 77mm filter ring – or for a host of other lenses as well.
This hood has absolutely minimal signs of use, and includes the essential 77mm non-rotating adapter ring, but no 360mm mask. Unless you are using a 360mm lens this makes no difference at all, because you do not use this mask with any other lenses. The instructions can be found in the Downloads section on this website.
This is much better than the earlier type G and G-2 hoods – and much harder to find.
