I still shoot a 5Dmkii solely due to the ML firmware. It's primarily a timelapse camera at this point. The ETTR functionality is one of my absolute favorites. The biggest drawback I have is trying to shoot with an interval less than 5 seconds. The ML software gets confused and shoots irregular interval shots. Anything over 5 seconds, and it's great. No external timers necessary for the majority of my shooting. I do still have an external for when <5s intervals are necessary. I'm just waiting for the shutter to die, but I'm confident I'll just have it replaced and continue using the body+ML rather than buy yet another body.
Thanks for your work keeping it going, and for those that have worked on it before.
