Manual Lens Usage Beginner's Guide

1.Why does my Nikon camera show 'No lens installed'?

Answer: A manual lens needs to be set to M mode.Turn the disc on the top of the body to the M setting.Nikon D90-3000-5000 series use M mode, while Nikon D7000 and above models can use A mode (aperture priority).Because there are no metal circuit chips and contacts, and no aperture linkage, the camera body does not display aperture values.(Note: The aperture value of the manual lens is adjusted through the lens), you can ignore the error message F-00 on the camera.
