Were both pictures with the same lens? Maybe a lens problem? I
understand Nikon may also ask you to leave the lens with the camera
because of the interaction between the two. Maybe a lens with a faulty
chip or an intermittent problem? The D100 does require more recent
lenses for accurate metering. Best is an AF-S lens which also factors
focus distance into the exposure calculation.
