5D markIII mirror lockup question

Yes. Live view can't function without the mirror being locked up.

In terms of reducing vibration, live view is even better than normal mirror lock-up as the camera then operates with an electronic first curtain so there is zero movement/vibration until the shutter closes mechanically. I'm 99% certain this is true of the 5D3, certainly is of the 5D2.

The 5D3's quiet shutter mode is also very good for reducing vibration. It works by slowing the mirror up/down, reducing noise and also vibration at the same time.

Thanks hoppy I didn't want to have to search for a setting each time I needed to lock it so that is good news.

Alternatively, you could add it to your 'My Menu' and set-up the Menus to always open at 'My Menu' when you press 'Menu'.
