As you have the E-M5 mk2 and the 12-100, have you tried the IBIS and OIS
together? If so, what improvement do you see?
It doesn't work as you assume it does. With the 12-100 mounted, the IS on/off entry on the body menu is grayed out. The
mechanical switch on the lens simply turns the coordinated IS on and off.
There is no way to do some sort of test of OIS vs. IBIS vs. combined. (Thank goodness!) Well, I suppose one could shoot
with a prime, IBIS on and off, then with the 12-100 at the same FL - and maybe also on a Panny body for OIS alone. Given
the variableness of testing human hand holding, and the range of shutter speeds to be tested, that shouldn't take more
than a few days to shoot and evaluate.
The IBIS of the E-M5 mk2 is already amazing, as in the robin image I just posted a link to. As a practical matter, the
vast majority of the stuff I photograph is natural stuff outdoors. As with the robin, Jim's recent bird pics, the many
insect pics I've posted, etc. most of it moves, a little or a lot. Even if there's no obvious breeze, the air is moving.
Plants and flowers move. Trees move - I've messed up by not accounting for that. IS beyond a certain point is no help
with these subjects.
Rocks, mountains, statues, buildings, and so on don't move in the time frame that matters. But for many/most folks,
that's tripod time. For me, out in the field, it's usually hold still, maybe lean against something handy, time.
Over the modest FL range of the 12-100 (by my standards), I wouldn't expect to notice much, if any improvement in
ordinary use.
As you might now guess, the OIS was not a factor in my decision to buy the 12-100. It's there, it's on, and I assume it
may help somewhere, sometime.
