Originally posted by Class A Obviously any longer-lasting exclusivity deal (a notion, I always rejected) would imply that Nikon is the mightier partner in the relationship with Sony.
Nikon, Pentax and Sony Imaging are nothing more than customers to Sony Semiconductor and cause Nikon is the bigest for big size sensors(APS-C & FF) one Nikon most probably has the lowest price and some exclusive deals as for 36MP FF sensor.
Originally posted by Class A I, for example, argued that Nikon really has no choice but buying Sony sensors (alternatives, anyone?)
Thats the bingo! Nikon has some intelectual properties on sensor design such as D3/D700, D3100, D3s and D4 sensors. Maybe Nikon threatened Sony Semiconductor to leave them as customer and continue only with Nikon designs if they do not lower sensor price.
Also there is Aptina which designed sensor for Nikon 1 and is working on APS-C and FF designs and that's another option for Nikon besides Sony.
