If you check your meter by pointing the camera at the sun and watching the needle go off the dial past f/22, that itself might be the cause of your meter reading wrong. The CdS metering cell might have been damaged by the extremely bright light or heat of the sun. However, first be sure it really is reading incorrectly. At an ISO setting of 100, an averaging meter viewing a scene with the sun behind you and not too much sky in the meter's field (which is typically smaller than the full viewfinder, likely about 1/2 that dimension in each direction) should give a reading of 1/100 at f/16, or 1/50 at f/22 (give or take the granularity of your shutter speeds; you might get 1/125 instead of 1/100, for instance). Or if shutter priority, ISO 100 with the shutter set to 1/125 should give an aperture of just wider than f/16 in the above conditions. Assuming this isn't the case, and with two cameras giving the same error, I wonder if you haven't turned on exposure compensation of some kind, or mounted a lens that's incompatible with wide-open metering on both cameras -- or damaged the meter cells. Does this happen with the original lens, or only with an aftermarket lens you might be trying to use on both bodies? Is it even a possibilty you might have a 1.5 V alkaline battery installed, when the camera wants a 3 V lithium cell, or some similar voltage error? |
