This adapter allows using lenses with M42x1 thread on Nikon-F cameras.
There is no ROM connection. Fully manual control. A camera can be used in either manual or AV (aperture priority) mode.
A lens in the adapter allows reaching infinity focus. But not every lens fits. Depth of the adapter is 8mm, so please check your lens at infinity focus - it's rear element shouldn't protrude longer that 8mm beynd the lens flange.
