This video is about 70D Demo. If you want a GREAT video about the difference between USM and STM lenses, go watch this video: youtu.be/djOPPQycZ8g You can really hear the noise in the focusing with the onboard mike. Now if you use a BOOM mic or LAV mic with the USM lenses, no problem, The touch focus on the 70D with a tripod would be great for shooting!
