Used Nauticam NA 67 Flip Lens Adapter M67 #20507. This adapter allows you to flip-mount M67 conversion lenses on an M67 port. It's compatible with those using single-lens reflex cameras, NA macro lenses, and other lenses from brands like Inon and Sea&Sea, as long as they have an M67 thread. Both the operation and appearance are in excellent condition with no signs of use. For those who need it, please take advantage of this opportunity. Shipping will be via Takkyubin (Japanese express delivery service). Please refrain from price negotiations.
