In this new video from tech guru (and certainly no Sony fanboy) Ted Forbes he explains why Sony is currently killing it. He explains that Sony’s advantage is more than just about sensor:
For example Nikon and Canon will have to launch a complete new series of lenses with new linear motors to really take advantage of the autofocus speed from the mirrorless system. not something that can happen in a very short time.
Moreover Sony is leading the sensor tech and Canon and Nikon certainly cannot beat them in any way right now.
