- may version:
Adjusting the aperture using an unchipped lens in live view (both photo and video) causes freezes and err70 or err80. I believe the err80 have something to do with turning the dial. Still investigating...
The first time this happened, it was not intentional, so I left it on for some minutes by accident. Then some traces from the frozen screen appeared both with and without ML. It was as it was burned into the screen. Luckily, it gradually went away within approximately 10 minutes.
