Reproduceable with 7D and 650D with different lenses (EF-S 10-18 STM, EF-S 18-55 IS II, EF 100/2.8 Macro USM (without L)
a) Motion Detection
- Use Autofocus ON
- Enable Motion Detection with default option
- Make sure to have cam directed to a well lit area able to focus.
- Leave menu by half-shutter press. Cam will enter Liveview mode
- Place an opaque object in front of lens. Distance < minimal focus distance. Give cam enough time to give up on focus.
- Remove object.
If there is no error, repeat steps 5 and 6.
