I put a demo video up on YouTube at http://youtu.be/irotrk8K6fc This is an 11+ minute video made holding the A7II with FE 35 2.8 out the window. All hand held. Sometimes my hand rested on the steering wheel. Sometimes I switched hands. Very amateurish but I was amazed by the smoothness of the video under bumpy erratic conditions The shake reduction system seems to have worked very well indeed.
