If I remember correctly,
it was discussed many years ago here that Pentax also held many
patents on various aspects of image stabilisation, mostly in
lens. I don't have the posts archived, and maybe the links are no
longer working, but it could be searched for perhaps. What I
remember is that the field was pretty muddled, with probably many
licensing and et cetera, and that the essential patents for
implementation of IS might be owned by several distinct
companies. It was discussed with great regret here that Pentax
didn't start producing its own IS lenses... Quite a long time
ago.
Good light!
