Well from what I'm allowed to say and know plus these great findings I'll hopefully give you some insight. These patents are all from Pentax and are very very new so nothing old here. Have a long look folks and feel free to research these yourselves if you'd like, but I'm too lazy to fake these diagrams and such.
Ok, First here we have a new wide-angle zoom system, hence the current patent date:
Here we have a macro lens with a floating lens design and from further reading it means great than 1:1 magnification by way of adjusting the lens.
Here is a Fast Zoom Lens patent, which dunno what it really means but fast is good.
New K20D anti-shake with Z axis added.
Z axis
K200D (from the looks because it has K10D controls, but no weather sealed door plus a Canon-like wheel in the back)
Well, thats all I got right now and like I said feel free to search the US patent office yourselves and study up.
Here is what Pentax has currently lined up while everyone was taking pictures and not too many people had mentioned.
1. Signed huge deal with the largest gyroscopic corporation in order to produce a better SR (Shake Reduction) system.
2. Signed a huge deal with Japans 2nd largest semiconductor and microprocessor company.
3. Hoya verbally announced that Pentax Imaging division will be a cash cow for the corporation and will devote plenty of money to back it (thank you Bloomberg).
4. Samsung is a great friend to Pentax now and will be giving them a few resources you'll find out about come this January.
5. Pentax had a run in with Dalsa, a leading CMOS manufacturer that makes sensors for aerial photography, so think of being to take a picture of the US continent and being able to zoom in and resolve a house; amazing stuff
6. Oh boy do they have a great camera in store! Sorry, but they do have them floating around, just letting you know it's happened under the news radar.
ANything else you want to know you'll just have to wait!
