All three pose a serious challenge to the existing order of things, undermining the supremacy of full frame DSLRs in the professional photography and video market.
Most image stabilisation systems are built into the camera lens but a few makers, including Sony, add a stabilisation mechanism to the sensor itself.
The 5-axis stabilisation in the A7 II compensates for 'angular shake' (pitch and yaw), 'shift shake' and 'rotational shake' (roll). Sony says it allows shutter speeds up to 4.5 stops faster, and it's designed not just for stills photography but video too.
The A7's mirrorless design means that you're looking at the live sensor image both on the back of the camera and in the viewfinder, so you see the effects of the stabilisation as you compose your shots.
