Could it be that the camera changes from matrix to centre weighted meetering
when switching to manual?

Here's the situation.  I was checking the results of a CLA on one of my
lenses.  Mounted the DS securely on my desk, set and locked exposure to
1/60 sec @ 5.6 with ISO of 200, took a few snaps of the wall.  This was in
Av mode.  Changed to full manual, exposure set to 1/60sec @ 5.6, 200 ISO.
Exposures look to be about one stop apart.  Results like this are
unacceptable.  Tried the scenario a number of times, making sure to hit the
AE-L button, making sure settings did not change, etc.  Must have run
through 50 or so exposures testing this. The camera consistently under
exposes when in manual mode compared to using the same settings an Ap
Priority.   Any thoughts?
