Aperture preferred automatic refers to an exposure function whereby the

On the istD, this is done thusly:
Set the aperture to the desired value.
Press the green button. The aperture momentarily stops down to the selected
aperture, and the camera sets the shutter speed, all by it's little self,
with no input from the operator.
Certainly not as seamless as on the fly AE, but since the camera is setting
the shutter speed itself, it is *not* manual exposure control by any
definition, other than your wrong one.
Where have you seen this "aperture preferred automatic" term? What you
are describing above is the behaviour of Hyper-Manual mode, as defined
in the Z-1p manual.
It is my least preferred mode on a camera, including the P modes of
the MZ-50, possibly because the button to press is fiddly and at the
wrong place for me. I only use it (without pressing the button, and
thus it is Manual mode) because it is closer to HyP than M on the mode
shift of the -1p. Of course YMMV, but this is HyM.
