Read this recently Pentax patent, the Pentax SR system is adding axes!

Btw, there is a body diagram for illustration purpose, but don't imagine too much for an upcoming "new" body. Look:-



Well, actually it is an *ist D, just! Just compare yourself!

From reading the abstract and flipping through the description, it seems that this is an ordinary 2-DoF system (X-Y plane). The new thing here is a mechanical design that prompotes simplification and miniaturization of the mechanism.

Oh really? Do I miss something? Should I change the title of my this post to "Pentax is decreasing DoF of their SR system"? :-o (As if what you say is true, the Yaw has been omitted in this design!)
