The patent for the 70-200/2.8 has been published." Fine by me.
I presume you are referring to the Japanese patent
No. 2012-189817, filled on 10 March 2011 and granted on 4 April 2012, or its US extension
N°US20120229689 filled on 5 March 2012.
Out of the six embodiments included in the patent, one is indeed for a 70-200mm f/2.8 with a 21.64mm image circle's radius, i.e. a 24x36 lens, but the other five are for a 15-45mm f/2.8 (f/2.9 actually) with a 4.65mm image circle's radius, i.e. lenses for a 1/1.7" sensor.
These embodiments correspond to the optical formula of the Q lens named 06 Telephoto Zoom 15-45mm f/2.8 and "
common sense" therefore prompts to consider this patent as being that of said Q lens and not of a 70-200mm 24x36 lens.
This patent is of no use for our debate and has no consequence as whether the 70-200ish 'Large Diameter Zoom' a.k.a. '* Tele Zoom' on the roadmap includes SR or not.
2) I am afraid you are making two mistakes there.
The first one is that
the picture you are providing a link to is that of the 'High Magnification Super Zoom' a.k.a. 'Tele Zoom' on the roadmap and not that of the 70-200ish 'Large Diameter Zoom' a.k.a. '* Tele Zoom' on the roadmap.
High Magnification Super Zoom a.k.a. Tele Zoom:
Large Diameter Zoom a.k.a. * Tele Zoom:
(click on any of the two pictures to enlarge it)
as evidenced by this picture taken on Ricoh's booth at Photokina by
Digital Camera Watch:
The second mistake you are making is that none of these two prototypes / mock-ups have three switches.
The High Magnification Super Zoom a.k.a. Tele Zoom (not the 70-200ish lens we are talking about, but anyway...) has, from top to bottom in the picture above:
- a lock, presumably a zoom lock to prevent zoom creeping
- a push-button, presumably a focus hold button
- and two switches.
The Large Diameter Zoom, the 70-200ish lens we are talking about, the one with the golden ring (star lens), has two switches and that's it.
In short: nothing you have written so far brings any evidence that the 70-200ish lens, a prototype or mock-up of which is currently displayed at Photokina, benefits from optical stabilisation.
