I just meant sensor ... eg. Fovenon vs CMOS vs CCD etc. But absolutely correct that the image engine or in film days the "processing" part do affect the final output more than whether it is Kodak, Fuji or Afga film; yet I am thinking that assuming processing is pretty much standard, different film does have its own unique characteristics? Not to mention that it can be of different ISO? Just my wild thought ...
that concept of course is perfectly correct, and thte key point is a standardized D&P. with digital, there is no such thing as a standard D&P though .. At this moment the GXR module concept is more useful to deploy not different made of sensor, but different kind of sensors ( size, pixel pitch, type of sensor ).
The APS-C ( or even FF ) would give the quality, but then it will not be compact, those 1/1.7 or 2/3 sensor can give a compact rum for the money, and in between might be the 4/3 sensor ( kind of not good enough to be compact, but not good enough as APS-C / FF goes if really critically examined )
The motto here is not the sensor , the concept as Ricoh puts that in their PR is combination of usage/need/lens/sensor/processing . So those convenience/compact/lightweight seeker can get the S10 module but live with the small sensor and all its good and bad. Those seeking quality can use the A12 module but had to also live with the size and bulk and all its limitation. Similar thing for future modules I would say .. in a way its not the typical main stream system as one used to see it ( though it can be in the future if Ricoh really put to it, but I simply do not see Ricoh going to go all out to do that )
I think its more wishful thinking believing for different sensor as stated. Its not really that viable to say get Foveon X3F in there ( Ricoh certainly had no imaging experience with the X3F ) nor Fujifilm's Super-CCD. Unless Ricoh would be able to struck a deal with those Mfr to cater their own module and sell them cooperatively with Ricoh. Fujifilm might be alright with that, but Sigma probably not.
Instead, Specialized sensor package module is likely more the case, say low MP count, but high sensitivity low noise sensor. Very high MP, highly resolving sensor but limited ISO, together with lens that cater to those sensors.
In fact the 2 module Ricoh give , an APS-C sized and 1/1.7 sized pretty much dictate the 2 end of the spectrum in sensor size. A FF sensor might be possible but I doubt it made sense ( the lens would then need to be so big it simply don't worth it ). One had to wonder if the 4/3 and 2/3 sensor might get a chance to appear in the lineup ..
