On the D however it's HyperProgram, and it jumps you into either
Aperture Priority or Shutter Priority depending on which you
shift (Tv wheel shifts into Shutter Priority, Av Wheel into
Aperture Priority) until you kick it back into Program with the

I still can't quite get understand the advantage. The KM A2 works
the same way that Pentax seems to label "HyperProgram", the Canon
10D works the more traditional single-wheel program shift. With
the Canon, if in Program mode, I can get either the aperture or
the shutter speed I want by rolling one wheel, and I return to
standard operation by rolling the same control back. On the KM or
Pentax, I can do the same but need to be aware of which wheel I
turn as well as what's changing in the viewfinder display, and
press yet another control to return to standard operation.
What's the advantage?
Not having used 'normal' program shift I'm only guessing, but:
1) With HyP, you control the parameter you want to control (speed
or dof) directly. With program shift, you change 'pairs': that
might be less intuïtive?
Well, as you shift one way or the other with the Canon's wheel, both
values change. Just as they do with the KM ... or Pentax ... right?
Doesn't really matter which control wheel you turn.
2) With HyP there is alomst no need to change modes on the camera
anymore, while Program Shift is different enough from Av and Tv to
make mode changes neccessary. You could ealily call that a
disadvantage as well...
Is it a plus that having HyperProgram you essentially have lost one
type of exposure mode control? You have Program, and either of Av or
Tv depending upon which wheel you turn. You change between them
fluidly ... but then if you had Program-shift like the Canon, you
simply pay attention to which of the two parameters you want to hit a
certain value.
3) I *think* that Program shift will follow the (shifted) program
line when the light changes, and possibly ruin your carefully
selected speed or dof. HyP will keep the required parameter (A or
T) constant, and only adjust the other. I think this is the most
important difference?
That's about the biggest difference. I don't really see that it's all
that important. If aperture or exposure time are that important, I'd
likely just use Tv or Av instead.
So the biggest difference, to me, is simply that it allows shifting
between P, Av and Tv without turning the mode selector.
