Reproduceable steps: Go to Focus screen in movie mode Adjust Focus End Point and change focus using arrow keys (scrollwheel) Change to menu item "Rack Fokus" Press "Play" button
-> Screen message "Rack Focus: REC Start" and focus will move (as intended) but after stop a message appears "movie end: Not recording". And no red record icon is seen in H.264 mode during whole operation.
Reproduceable on 7D as well. 100D works a little bit different: Won't do run Rack Focus by pressing Play at all. Just switches to ML menu.
Rack Focus by pressing SET works as intended
And Q button not starting Rack Fokus at all. 7D, 650D as well
