I'll keep my 645Z for the moment, but at $1800 the FF K-1 is looking like great value.The difference seen at Imaging Resource is quite striking.

I believe that Pentax is using Pixel shift to create a composite image that remains at 36 megapixels instead of creating a ~90 megapixel image. The point of their pixel shift is to get a read out of every element of the scene by at least one RGB pixel under the Bayer filter then create a composite 36 megapixel image from all read outs.If multishot - AKA sensor shift, AKA pixel shift - as been properly implemented, you can expect close to double the resolution compared to single shot mode. A 36mp sensor in multi shot should thus equate to roughly around 60-70mp in single shot.
Better hope the lenses are up to it.
Correct, the composite image remains at 36 MP. As I understand it, in shift mode each pixel is exposed four times, twice through the green filter and once each through red and blue, measuring RGB vales at every pixel. The advantage of the Foveon achieved by a different mechanism.I believe that Pentax is using Pixel shift to create a composite image that remains at 36 megapixels instead of creating a ~90 megapixel image.

This creates more accurate and sharper images... Not too different to how some have used a panchromatic version of a scene blended with a color version of the same scene to increase perceived sharpness.
Exactly. What I should have written in my original message is double the effective resolution, because the result is a much sharper image free of moiré that, scaled up, will almost be a match for single shot with double the pixels. The same is true of 4 shot multishot with a Hasselblad H5D multishot camera. With multishot, the image is still 50mp, same as single shot capture, but bayer interpolation has been eliminated and true RGB info gereated at each pixel. Looks like the Pentax works in a similar way.I believe that Pentax is using Pixel shift to create a composite image that remains at 36 megapixels instead of creating a ~90 megapixel image.

Perhaps we can adapt our 645Z lenses to the K-1.The multishotsamples are really impressive.( One could also say its impresive how washed out the fabric from the single/normal shot looks after seeing the multishot image.)
I am loking forward to see more real world images from this camera. Even though I am comitted to other brands systems and not planning to switch, the K1 looks like an impressive camera.
Manual focus adapters are available. I have them for K mount and m4/3.Perhaps we can adapt our 645Z lenses to the K-1.
It certainly is and interesting an remarkable camera. I saw some stunning photographs with it . I like the sturdyness of it and it is reasonable small as well!A UK review posted high ISO downloadable files yesterday. They looked pretty stunning. The DR and ability to recover shadow detail pretty much seems to meet expectations and be a close match to the 645Z. The K1, with it's unique feature set, has the potential to cause some major ripples in the landscape and studio DSLR market just as the 645Z did with the DMF market.
