Fantastic, I'm not a left-hander, but this is perfect for all Stereo Photographers. (They didn't say that, but that was the main target. )
The camera has options to sync the lens and other functions for that.
The handles are perfect for this - when mounted in pairs - to take movies with it, no extra gear needed, just the "Canon "Bridge 04/01" to get both mounted.
It's only to sad that this is only today available and the next order can go placed in exactly one year. ;o)
