Sony A9 5-axis image stabilization?
« on: April 24, 2017, 09:34:15 am »

I don't understand what this means. There are only 3 axes in a 3-demensional  space: pitch,yaw and roll.
What am I missing?

The translation axes: x, y, and z.

There are 6 degrees of freedom, 3 translation and 3 rotation.

Yes, one wonders about that 'missing' sixth: the fore & aft unintentional 'zoom' effect.

Got it. I forgot about translation, which is rarely obvious in the movements of ships or aircraft.
And a mea culpa for misspelling "dimension".

Thanks,
