This lens hood was designed for the Fuji GX680 Medium Format Camera's 65mm and 80mm lenses.
The lens hood is metal, of the slip-on design, allowing it to fit over lenses having an outside diameter of 100mm, and typically having internal threads of 95mm.
Included is the hood extension ring, which has 110mm x 1, male and female threads and an extension of 20mm.
The hood works great as I tested it by mounting on my Schneider SAXL 72mm Lens. The set screw is slightly bent, however it worked fine, with no binding.
I also checked the extension threads, of course by attaching and detaching from the primary hood section, but also by checking the female threads of the extension by mounting to my APO-NIKKOR 610mm Lens. Perhaps this is too much info for this listing, but this hood makes a great accessory for the Large Format lenses mentioned.
Please feel free to message, should you have any questions in regards to the mounting and compatibility, though I am not a Fuji 680 user or owner.
Your Fuji Lens Hood GX80 will ship within one business day of the receipt of your PayPal payment, which is due within 12 hours of the listing's end.
