Non-CPU lenses can only be used in mode M, when aperture can be adjusted manually using the lens aperture ring. The cam- era exposure meter can not be used. See “Optional Accessories” (105).

If the limits of the exposure metering system are exceeded, one of the following indi- cators will be displayed in the control panel and viewfinder:
