Read carefully Peter. The note on page 308 is a troubleshooting guide
that tells you what to do if shake reduction doesn't work. It says
that when panning or shooting at night with slow shutter speeds, it
may not work. In other words, SR won't eliminate shake in a slow
shutter pan. I already know that. But there's no need to turn it off
when shooting a slow shutter pan. I know that, because I do it. And
doing personal experimentation is always the best way to arrive at the
truth.
After 6000 frames I've found for certain that one never has to turn
off SR in the K7. Would you like to see more evidence?

I would assume that the PDF file I linked to is the latest manual.
If you open that PDF file in Acrobat, select the "Pages" tab, and
click on the page labeled 310 it will take you to the page numbered
308. Under the column headed problem, scan down the page to "Shake
Reduction Doesn't Work". I tried to make it easy. Of course you
can simply open the acrobat reader search function and type in
"Panning" it will take you to the same page. In fact it's
apparently the only place Panning is mentioned. If they thought it
wasn't important it wouldn't be there. It's not opinion, it's
documentation, if you think it's wrong you should contact Pentax. I
don't think it's wrong.

Page 310 of the K7 manual deals with SD card capacity in different
modes. Page 2 of the PDF at the Pentaximaging.com site says shake
reduction can be turned off when panning. Doesn't say it has to be
turned off. I know that great pan results can be achieved with SR
left on. I make judgements based on results rather than on the
opinion of others.

To everyone who thinks the Pentax has decided that SR can be left
on while panning, perhaps they should update their documentation.

I'll leave it as an exercise for the student to check out the
manuals for the K10D, K100D, K200D and K2000/K-m. But I'll wager
they all say it's best to turn off SR while panning, as well as
while using a tripod, taking macros, etc.
I think I'll take the word of the Pentax engineers and marketing
folks that SR should be turned off, I tried a couple of panned
shots of flying birds and they came out looking double exposed. I
deleted them but I'm sure I'll forget to turn SR off again, and
I'll post some samples.

Removing the switch and making it a small production to turn SR
on and off shows what I think is a "Point and Shoot" design
mentality the same thing that resulted in the focus control
debacle, This type of mentality doesn't belong in the design of
a relatively high end camera, hell, it doesn't belong in the
design of Point an Shoot camera.
Unlike the focus point issue it looks like it's not an easy a
fix, what with the hardware switch being gone and all...
Most of my photography of dogs is either panning or hoping the
'predictive' auto-focus will afford me some good shots. As far as
panning goes, I never turn SR off, and my opinion is it has
little effect on the sharpness or quality of the resulting
images. I rarely remember to turn it off when I'm on a tripod
with a remote release!
What I'm saying is that Pentax probably realized that in fact
leaving it on all the time for an outdoor shooter, or off all the
time for a studio shooter, was not that important a deal. Given
that their users weren't complaining, they relegated the switch
function to a less intrusive menu item.
