I am wondering why Canon put this sensor into 6d - the 5d3 seems to have the 22mp count because it's a multiple of 1080p and produces less moiré when downsizing to video resolution.
Is there any reason for the the way the 6d sensor is *except* marketing, i.e. keeping the tech spec even below the 5d2's 21mp? Maybe Canon gains a significant production advantage like less sensor waste for 6d and such is able to lower the price? Or is there any video- or stills-shooting related reason except that a little larger pixels produce a little less noise?
