On the DL, my procedure for metering and using an "A*" lens:
- Set M mode
- Frame picture (make attempt at composition)

finder).
- (still holding DOF preview) Hit AE-L
- Relax (finally release DOF previe- start physical therapy on
thumb)
- Trigger shutter (subject has left the area).
With an A series lens, you shouldn't have to do anything with the DoF
preview lever to meter. Set M mode, set lens on "A", aim at target,
use thumbwheel to set aperture, touch the AE-L button. It will now
say "0.0" in the viewfinder, and the shutter speed was set to
complement the aperture. Adjusting the shutter speed or aperture
after this will read out the difference in the range EV +/-3 from the
metered subject if you keep the camera on target. Complementary,
retarget for another subject and you can see the difference in the
exposure required by the meter.
Touching the DoF preview lever should blank out the metering
readout ... the lens stops down and the meter, with an A lens set to
"A", does not read out with the lens stopped down.
If this is not happening, I suspect that either lens or body have
dirty contacts or a bad connection.
