No, there's a gyroscope in the lens that detects the direction and
amplitude of the motion and commands the shift of an internal lens
group in the needed direction and amplitude to compensate for the
movement.
It needs however support from the camera part:
- powering;
- signal to know when to start the stabilization sequence (on shutter
button half presses);
- it needs to send a signal to the camera when / if stabilization
is successful to allow triggering the shutter.
Nothing overly complicated, the KAF2 mount with its power-zoom
contacts could support the IS very well with minimal additions in
the digital protocol.
