I was asking about that exact post. You state that the system only shifts the sensor in rotation about the horizontal axis (which I take to be the optical axis). So does this system compensate pitch and yaw only using vertical/horizontal translation?

Pitch and yaw are corrected by shifting the sensor up-down and left-right. All in-body IS systems do this and work like that.

Thanks. I understood previous in-body systems to work this way, but I had wondered (from the name?) if the Olympus system actually corrected for multiple rotation axes. It seems not.

I don't think you're understanding correctly.

Sorry, I should have said "corrected using multiple rotation axes." You can see from the previous post that I was talking about pitch/yaw compensation (two of three rotation axes) via sensor translation.

Sorry. My mistake.

I think the biggest misunderstanding of the E-M5 IBIS is that it's the 5-axis part that makes it great. The additional two axes are only valuable in limited circumstances and in fact those corrections can't be applied with most lenses. The lens has to be able to communicate its current focus distance to the camera in order for X and Y-axis translation correction to be done right. None of the m43 lenses that I have do that and obviously no adapted lens will either.
