Seen this article this morning. So far, it look pretty cool :
Ricoh reveals pixel-shifting high-resolution mode: Coming soon to a camera near you?
So far and roughly, it seems that this will be incorporated into the upcoming Pentax FF by the end of this year. What is interesting is that the multi shot will be quicker than the Olympus tiny m4/3 (only 4 shots) and the picture will not be stretched : they will keep the spatial dimensions. Full RGB native pictures.
With the actual "Faux Veon" development ... I do not see any future for SIGMA cameras if brands start to go full RGB way. There will be no point at all. The only way to counter that is if SIGMA come with a 1/1/1 24x36 architecture.
The Next SD will probably be priced into the 2000$ range, probably APS-C quattro. The Pentax will come into roughly the same price range (guestimate).
I used to shoot a lot with Pentax before I went into FF and those are good cameras; the lenses aren't bad either. I heard that SIGMA will probably produce their lenses in K mount so... what is the point of going SIGMA way if they lose even their sheer specificity ? This is the question I'm asking.
