Camera Settings (continued)
3.When a manual focus lens is attached, some Nikon cameras allow you to enter the focal length and the brightness. With these Nikon cameras, you can use the lens more efficiently by entering the focal length and the brightness.
For some Nikon cameras, if you enter the focal length and the brightness, and set the desired brightness by turning the aperture adjustment ring, the camera automatically changes the shutter speed. Therefore you don’t have to adjust the shutter speed as well, which is required in M mode.
(Note: Camera settings are different depending on each model and are subject to change due to functional enhancements. For detailed information on your camera’s settings please refer to your camera’s manual or contact the camera’s manufacturer.)
