【NO electronic contacts and No Autofocus Motor】Manual lenses lack electronic contacts, so you need to use our lens in Mode M. In the meantime, you must set the ISO/Shutter speed in mode M, otherwise the photo will come out too Bright/Black. On manual lenses, the camera may display F-- because it doesn't have direct access to the aperture value.
