This adapter features a diaphragm control ring for adjusting the diaphragm of Nikon's G series lenses. It fits Nikon AF-S G & F mount lenses and F mount lenses from other manufacturers. It is also compatible with Nikon F & Ai mount lenses.

Material: chrome-plated brass and anodized aluminum.

There is no ROM connection on the ring, so the lens diaphragm is adjusted manually. Macro rings and other accessories can be used. Brand new, it has never been used. It can focus infinitely.

WARNING: Although the lens fits physically, the automatic diaphragm, autofocus, or any other functions will not work properly when using this adapter. In this case, "stop-down mode" should be used during metering, as the lens cannot control its diaphragm from the camera body. You can shoot in manual mode or aperture priority mode.
