Panasonic 12-32 on Olympus bodies

The 12-32 works amazingly well on an EM5 and EM1. At f/4 I could barely tell it from the 12-40 at the wider end. Even at 100% crop it really holds up to the corners. MUCH sharper than my 9-18 in the overlap range. It did have a little PF (12-40 is auto corrected) but it came out nicely using the LR5 tool.

I have started carrying the 12-32 on my E-M5 to make it more pocketable, but I am not sure if I should turn IS off (which means both IBIS and OIS I believe), or leave it at IS-1 and let the two systems sort it out. I guess I will need to test it.

The E-M5 has the early firmware that cannot control unswitched OIS so the 12-32mm OIS defaults to always off. Using IS-1 will only control the body stabilisation.

Later bodies have a Custom Menu item of "Lens IS Priority" so can they use unswitched OIS.

What have others found? Is dual IS better or worse than no IS? Does it depend on conditions? btw, I have switched to 1/4s anti-shock after seeing SS at 1/8s and 1/125s exposures. Not sure if this made worse by having two IS systems working at once.

So, only the body stabilisation can work, and that would be preferable to lens OIS because OIS is always only 2 axis correction, and the E-M5 is 5 axis correction, that adds the roll correction as the third axis. The remaining two axes are parallel body shift up/down/left/right which matters more for macro. I would say the 3/5 axis stabilisation would be way preferable for extreme cases, such as a video while walking.

If you could have two stabilisation systems working together then the results would be a disaster. (possible with E-M5 and earlier bodies and a switched OIS lens, impossible on later cameras as they interlock to one only functioning).
