It hit the business news sites on Saturday that Toshiba may be selling their sensor business to Sony.
If you read the blogs you will hear that Sony design and manufacture sensors for Nikon and others. Well maybe the lower end cameras use Sony designs but the higher end models are Nikon designs manufactured by a number of different contracting fabs.
The majority of Nikon sensors are made by Sony but Toshiba also manufacture sensors for Nikon. This will certainly strengthen Sony’s position and weaken Nikon’s.
