"Have recently the Panasonic 14-140mm. The main reason for buying was of course the zoom range to extend my 14-42mm. But had hoped for a better stabilization. The 14-42mm is according to Panasonic equipped with a Mega OIS. , the 14-140mm with Power OIS DC doubled compensate for camera shake promises Panasonic. The greater my disappointment when I compared with the 14-42mm. I see no advantage for the 14-140mm. ..... It is virtually impossible from the hand to take video that do not wobble. I do not mean gross wobble. It this fine, unpleasant to be regarded wobble. Especially "vertical rotation". The 14-42mm is there even a little better.Unfortunately. ......Too bad that the stabilizers of camcorders are soooo much better than the built-in lenses.

@sportster:

"I think that compared to the Mega OIS of the Power OIS brings improvements at most in photo mode. For video, the "improvement" cast so that the quite natural-looking large-scale shaking of the entire video image is replaced by a behavior in which individual elements of the subject are indeed stable, but might move against each other dynamically.This leads to an unsteady image impression one might almost be called fibrillation. Perhaps this impression is also created by the limited sampling rate of the sensor........ It only helps a stable support or a tripod. I myself have already tested several Panasonic lenses and have come to the conclusion that me the Mega OIS was better for video. The Power OIS  seems to be implemented differently, depending on the main target group of the lens (photographer or videographer). Most striking is the negative video-flicker effect in my opinion just the sharpest and most expensive lens, the 35-100 / 2.8. For this affect the stability of this lens in photo mode phenomenal. Best behave in the video PZ lenses, so the 14-42 PZ and PZ 45-175. Especially the small and lightweight PZ 14-42 produces the quietest video images, even though one would think ought to that larger and heavier lenses in the advantage would be. The new 14-140 lies with its implementation of the Power OIS somewhere in between. The old 14-140 with its Mega OIS produced slightly smoother video recording, ........ the Power OIS effect is barely disturbing due to the wide angle characteristics, but is also visible when one pays close attention.
