This sale is for a brand new Mamiya 7 150mm f4.5 Lens Hood, suitable for use only with the Mamiya 7 / 7ii 150mm f4.5 lens.
This hood is boxed, new, and with no signs of use.
This is the proper bayonet-fit Mamiya lens hood, not a cheap screw-in clone. Try finding another one – these are almost impossible to find.
