by the way, no firmware can add ois to a lens without the ois motors and controllers. I think you mean DIS, digital image stabilization.

In-body OIS is already there, just not used for video.

OIS is optical image stabilization. You are confusing it with ibis, in body image stabilization.

The IBIS is optical. It is used for stills, i.e., it is OIS; for video, somehow Oly decided not to use it but use digital IS instead.

To be exact, the IBIS is sensor shift.

OIS is lens IS, sony call is OIS for the mount, panny calls it Mega OIS. OIS is meant for lenses, as it is the optics. IBIS is IS for sensor, or sensor swift to be exact.

The movement is relative between sensor and glass, it does not matter which is chosen to shift. Both can be considered as optical IS, not digital IS.

optical is lens, sensor shift is is not optical, you can call it ibis or sensor shift. But it is not optical. Or just call it IS.

Optical IS has two implementations: in lens or in body (sensor shift). Both are optical.

I will agree to disagree. because the ibis companies define their systems differently form the lens base companies. So it comes down to who's definition you go by. So in M4/3 world ibis is oly, ois is panny.

In german lens is objektiv, with ois has a more constrain meaning. That is one of the reason that the camera brands define them way more precise then wiki, as they are international companies.


google turn up a bunch more

Yes, it's a matter of definition. The point is: PEN's IBIS is as effective as in-lens OIS of panny, if not better. Unfortunately Oly disabled this feature for video and use digital IS instead which sucks.
