Hi.
I'm planing to buy external monitor so whoever helps me with shoot can see what's happening.
Is it possible to mirror 5DmkIII screen, not just transfer image to external display? Like it's with 1.2.1 firmware?
Couldn't find any setting for this in ML menu. But I really hope it's somehow possible.
Topic has been discussed numerous times if you search.
Answer is no, can't mirror the display, best that you can do is lose the camera monitor and watch the image on the external one, not both. Even with that, it's not perfect and some people have been running into weird issues, but it's a hell of a lot more workable on the 5D3 than on the other cameras.
