This sale is for a super rare mint condition RB67/RZ67 37mm Fisheye Filter Set – suitable for the Mamiya RB67 and RZ67 37mm f4.5 fisheye lenses. Please note that these 40.5mm screw-in filters are specially shaped for use with the fisheye lenses and are not really suitable for use with other lenses.
A UV filter should be fitted to the rear of your fisheye lens as standard; one filter should always be attached to the lens. Simply unscrew the UV filter and replace it with one from the case. The instructions for doing this are in the Downloads / RB67 and RZ67 sections on this website.
Really hard to find – a super rare item. Grab it while you can!
