Did you use the touchscreen with a longer lens? I had a sony hdv/dvcam A1 which had touch screen and even with the slightest contact the camera wobbled at telephoto.
I wish Canon would introduce lanc control off camera, maybe the stm lenses are a move towards that?
Did you use the quality scale setting? Interested to see if you can attain a higher bitrate than with T3i.
