The roll axis was made thinking in a Head-Mounted Display (HMD).
Think, in a standard LCD monitor, if you rolls your head, the monitor stays in a fix position and the roll axis has a terrible effect because you loses the orientation of horizon's line.
But, in a Head-Mounted Display the display follows your movement because it's Head-Mounted, of course, then you needs the roll axis to see your movement.
Conclusion: in my standard LCD monitor, I need to disable the roll axis, but it's perfect for HMD's.
And, if you can see, the external zoom begins after you are closely the panel (internal zoom).
