The camera probably just treats the lens as completely stopped down and
adjusts the shutter speed accordingly. It's probably like the older non-AI
Nikon
bodies. When you set them up for stopped down metering, you just pushed the
metering arm up inside of the metering head and the meter was "nulled" for an
average value of f/5.6. The camera's meter just read the light value as a
"dark"
f/5.6, or else a "light" f/5.6 and indicated either over, or under exposure in
the finder, (for manual bodies).
When using auto-exposure bodies, up to, and including F4's, you'd simply flip
up the metering lug, just as if you were using either a bellows, or a mirror
lens, put the camera into aperture priority AE, focus, stop down to the
"taking" aperture setting and shoot. Of course you'd have to make adjustments
for
overly bright areas or dark areas. I also found that while using the F4 body,
matrix metering was available in all modes, with any lens and corrections were,
for the most part, unnecessary.
Just a thought.
