Manual lenses with F80, F75, F65AI- and AIS-type manual focus Nikkor lenses, as well as Nikon Series E lenses, will mount on an F80, F75, or F65 but the camera will provide very limited functionality. It will confirm focus and provide a full range of manually set shutter speeds, but the light metering system will not operate. The aperture and shutter speed must be set manually based on estimation or an external light meter. Print Share By Email Share By Social Ask A Question FaceBook Twitter
