I can't comment on the specifics of the camera Jim, but I would suggest that
the two scenes are not "identical lighting".
Just take a look at that *huge* area of white garage door right in the
middle of the second frame. I reckon the camera metering has made a very
good attempt at rendering that in the regulation 18% grey (OK, gray). That
is what it should be doing. But now look at the same door in the first
frame - it's partly obscured by the main subject, and the camera position is
further away, reducing its proportion of the image. And it isn't in the
centre (OK, center!). I assume that the apparent strong evening sunlight in
the underexposed image is exaggerated by the exposure, and the same lighting
was present in the first exposure, but washed out. But I strongly suspect
that the sky was not as bright white as it has been rendered.
1 frame is overexposed by one stop, and the other is underexposed by one
stop, most likely attributable to the unusual tonal composition. I wonder
how OM-PC ESP metering would have coped?

Nice shots Tom. I can't say I haven't gotten some myself, but here two
classic examples of how the metering works on my camera. Please! No comments
on content. Sometimes you have to use a camera for snapshots...

Both of these were shot raw, aperture priority mode, ISO 200, matrix
metering, tone comp auto, no saturation adjustments, white balance set to
cloudy, noise reduction auto, standard curve in the camera. All I did was
convert them to jpg and downsize for the web in NC.
Lens was set to f/5.6
Camera determined shutter speed on the first was 1/250 On the second one
1/60
IOW, there is a full 2 stop difference in what the camera determined was the
correct exposure, even though the shots were taken in identical lighting
less than 2 minutes apart. Can someone look at those scenes and tell me how
I could look at them and determine I needed to add *2 stops* of EV comp to
one to get an exposure that's similar to the other? If anything, I'd think
the camera would have underexposed the primary subject in the second frame
given the amount of sky showing. My OM's sure would have using center
weighted metering. What I'm seeing is the opposite of what I'd expect. But
who knows, maybe I'm just not that good at reading a scene...;)
