FotodioX Nikon G to C-Mount Pro Lens Mount Adapter with Aperture-Control Dial

The Nikon G to C-Mount Pro Lens Mount Adapter from FotodioX allows you to mount your Nikon G mount lenses, both FX and DX, onto your C-mount camera and maintain infinity. The adapter's blue dial enables you to manually control the lens's aperture for exposure control, which G lenses normally need to have controlled by the camera body.
