Pentax full frame 35mm official announcement from Ricoh (K-1 36mp)

[tduell]

I'm confused.

Does the K1 do four takes for each image ?

Yes, the same as the K-3 II does. It shifts the sensor by one pixel for each shot with each aligning exactly with an R, G, G and B of the Bayer pattern, then saves all 4 in a DNG (or PEF) or if shooting jpg does in camera processing to emit one standard size jpg PS image.
It might be useful to do a search for "Pentax pixel shift"...there is quite a lot of material on the web that explains it with nice images, probably much clearer than I am doing it.

Cheers,
Terry
