While shooting some concert footage, I needed to see if I underexposed. While recording, I changed the value of underexpo. I heard the IS shut of a fraction second after the change, and a second after that the error70 occurred. Luckily the file was saved, but when recreating the issue, the file is sometimes saved, and sometimes not.
