Every OIS/IBIS system I have used has at times messed up my pictures instead of helping them. Most of the time they are great, but every so often you will get some crazy image where the system didn't do the job properly.

I think there is a point of diminishing returns with image stabilisation ; it's great to just get the shot, when conditions are very challenging, or when ultimate IQ is not a major concern .

IS is almost always degrading IQ, IF there is a choice to not use it , but by how much depends on the circumstances .

We talk about sensors and software recording and anticipating movement, adjusting lens elements or sensors in split seconds, and there might be a little image correction involved as well, even with Raw files .

The OMD E-M5's multi-axial gyroscopic IBIS is so very good that it needs to be considered in a whole new context.

And yet people are reporting problems wit this IBIS system.

as far as I see it IS is a tool, when used right, it will help you, when used wrong it will hurt more then it helps.

People need to understand the limmitations of this tool. Sometimes it is better when you do not use it.

Zeiss knows what they are talk7ng about. they make l3nses with very high quality, IS in a lens will degrade the IQ by adding a lens group that yas to be moving, making it not totaly predictable, so it will introduce some problems, like the IBIS of the OMD (and other IS systems)  do.

In a way the tripod is the best IS there is, but not the most convinient one...

Of course and many, perhaps even most times, IS is not necessary. But give credit where credit is due. The Olympus OMD's IBIS is superior to the NEX OSS, or to Panasonic's OIS.
