After incompleted unstalling the latest 1.2.3 MLbuild (Nightly.2015Jun09.5D3123), i had incompleted boot on my 5D mark 3.
On boot of my 5D mark 3, camera don't make cleaning of the sensor, takes itself a picture. Autofocus operates but release is impossible. Release is only possible after each visualization on the screen of a picture.
Somebody has already this problem ?
