There is rumoring that the next Canon sensor is going to use a modified Foveon setup with the sensor built by Sony.
Thats awesome, the a7s is a beast. Now what happened to all the chatter about these graphene sensors? Im sure that will blow our minds when the time comes. Also, i have always thought a 3 point selectable hdr would be cool, so select the highlighhts, mid tones and shadows to get a proper hdr exposure. Twould be nice.
