Actually I don't think that Pentax licenses there version from Sony,
IIRC they use a very differnt system based on some sort of magnetic
levitation as opposed to Sony which uses ball bearings actuated by
magnets. The only thing they have in common are the magnets. On the
other hand, the only thing Poloroid patented instant film process had in
common with Kodak's was osmosis, which being a natural phenomenon, I
didn't think was patentable, but hey Kodak lost.

Sony does with their full-frame DSLRs. Pentax licenses the in-body
stabilization technology from Sony.
I figure Nikon & Canon already have too much investment in their in-lens
IS to ever change. I see that as a shortcoming on the part of CaNikon

Can you do in-body shake reduction with larger sensors?
I doubt the N or C would put it in the body anyway. They make too
much money on the lenses and have spent too much time telling everyone
that it's better when it's in the lens.

I'm not sure how much scaling up would be required the hypothetical FF
Pentax would require for a FF mirror box. If you compare a *ist-D
and a
*ist-Ds and an ZX/MZ-5n, you'll find that the *ist-D has the same size
mirror box as the ZX/MZ camera and the *ist-Ds camera has a mirror
box and
mirror more in keeping with an APS-C sensor. Yet it isn't appreciably
smaller for that, the volume just seems to be distributed
differently. Now
the shake reduction system might require a slightly different form
factor,
but then again it might not.

I ran across this in a discussion thread in DPReview comparing the
Nikon
D600 to the Nikon D7100.
I've mentioned here before that I've been looking closely at the Nikon
D600 and consider its specifications to be a minimum starting point
for
what any Pentax FF must offer. Still, it has some shortcomings from my
point of view (beyond Nikon having put their IS in the lenses).
Someone mentioned the D7100 as an example of what a Pentax K5II
follow-on camera would need to be, so I took a look at its specs on
DPReview and it seems to have fixed every concern I had about the D600
(other than IS which I understand ain't gonna' happen).

Semi-OT because the author bases his design of a hypothetical
compact FF
Nikon "D800c" on scaling up the the Pentax K5 body to fit in a FF
sensor
& mirror box.
The rest of the article doesn't matter all that much, but I thought it
was interesting for the suggestion that Nikon should be taking design
cues from Pentax.
