Originally posted by asw66 I'll say this much for Nikon -- they've stitched up deals with at least three different sensor manufacturers, to my knowledge: Sony, Toshiba and Aptina. If they can maintain these relationships (perhaps with some degree of exclusivity), this places them in a very strong position for future innovation.
Naturally, I hope that Ricoh/Pentax are able to cut similar deals, and not be locked out of any promising technologies.
Nikon is Nikon. They don't leave things to chance. They may underestimate the market for a while, their appetite may be bigger than demand, but one can rely they'll be always ready to provide robust, conservatively designed, relatively unimaginative but mainstream-looking camera.
As such, they have more buying power, and can negotiate more, get better deals. Let's not be surprised if Pentax is not making any FF announcement yet because what they can get from a sensor manufacturer, is not same as what Nikon can get. Pentax probably must wait, and wait, and perhaps will wait untill Sony ramps up their FF mirrorless line, and Fuji joins in, and God-knows-who-not — even Casio — just to be able to make a camera
they believe their customers are willing to buy.
I would not be surprised if Nikon sells more FF cameras alone, right now, than Pentax sells all its APS-C DSLRs together. When just about everybody delivers an FF camera of some kind, Pentax will eventually come. Will they be last ones? Most likely.
I simply don't believe Ricoh will do anything to raise Pentax's sensor credit rating. They will just milk it slowly, and steadily, and allow it to graze — just enough to stay on its legs.
