When used with lenses that do not have the A setting on the aperture ring, the AE-1 cannot do autoexposure. Aperture and shutter speed have to both be set manually using stop-down metering. The "blinking M" in the viewfinder is normal in this case. To do stop-down metering, push the depth of field preview (aka stop-down lever) in and lock it. Looking at the front of the camera, this lever is on the lower right side of the lens mount. Focus with the aperture set wide open so that the viewfinder is bright, then adjust the aperture and shutter speed such that when the shutter button is half-pressed the meter needle in the viewfinder aligns with the battery-check/stop-down mark (next to "5.6"). Leave the stop-down level locked down so long as the lens is being used on the camera, but you must release it to change lenses.
