Neither HyperProgram nor HyperManual are exactly the same as
using a Super Program and switching between manual & auto
shutter speed selection.
You don't mention whether the lens is set to the "A" position
or not, so I'll address those cases separately:
1) Lens set to "A".
(Changing the shutter speed selection mechanism results
in switching between "P" and "Tv" modes of operation.)
This is (a subset of) HyperProgram mode. To switch to
Tv operation, simply adjust the shutter speed wheel.
To switch back to "P" mode, push the green button.
That's rather simpler than moving the mode switch on
the Super Program. You also get the ability to switch
to Av mode by just adjusting the (rear) aperture wheel.
2) Lens not on the "A" position (includes older lenses).
(Changing the shutter speed selection mechanism results
in switching between "Av" and "M" modes of operation.)
HyperProgram and/or HyperManual modes don't mimic this
mode of operation too well. Not only that - behaviour
differs depending on which HyperCapable body you use.
On the PZ-1p, for example, moving a lens off the "A"
position while in HyperProgram mode automatically puts
you into "Av" mode. Attempting to change the shutter
speed by adjusting the front wheel has no effect; it
doesn't automagically switch you into manual exposure.
On the *ist-D, which lacks the ability to detect what
aperture is selected on the lens aperture ring, moving
a lens off "A" while in HyperProgram mode gives you an
almost useless kind of "Av" mode; the setting on the
lens aperture ring will be ignored, and both metering
and exposure will be done at full aperture.
HyperManual mode behaves much the same on both bodies.
Pushing the green button causes the camera to meter (using
stop-down metering on the *ist-D), and adjust the exposure
appropriately based on the light level. Whether this is
done by adjusting shutter speed, aperture, or both depends
on whether there is an "A" lens mounted (if not, the only
choice is to adjust shutter speed), and by a user-selected
Pentax Function. But in any case this is a one-off operation;
if the light changes the camera won't automatically adjust
the exposure again.
