As for unique features, among them (for a full frame) is the Astrotracer, Composition Adjustment and Pixel Shift.

 

So, it's all about shaking the sensor around, yes? I'm sure it's only me, I just don't recall the last time I missed the uncertainty of "what is this sensor doing while I think I switched every movement of it?" And why I never missed that open answer to the question "I DID switch sensor movement OFF, didn't I?", I'm sure one can do anything with the moving sensor feature, cutting jigsaw-puzzles, getting the coffee milk  stirred and with some accessories share some satisfying erotic encounters - but taking good pictures?

 

K-m and K-x were already doing sensor mumbo-jambo and I never got a decent picture without some flaw out of the combination Tamron 17-50/2.8 wide open and one of the Pentaxes. The pictures I liked were nearly all catched with a Sigma lens. Therefore I do have some slight doubts. My Pentaxes never made a picture without front- or back focus - so, if they can't get the AF straight, how do they want to move a sensor for exactly one pixel in any direction?

 

As well the moveable screen: Technically an interesting solution, but not as versatile as an articulated 180° × 270° LCD like a lot of Canons offer, Olympus and Nikon's 5xxx series. So, what's the point?

 

Personally I like the compact design if it, it reminds very much on a small scale medium format, as deep as this body is. The price is also pretty tempting giving what you pay other producers to get hands on a 36 MP sensor - but as usual, you get what you pay for.
