Oly 12-100 IS switch.

When used with an E-M1:2 IBIS what is the purpose of the IS switch?

When would one use it on/off or with IBIS on/off

Cant seem to find a simple/adequate explanation.

Perhaps on a tripod??

Some say not to use IS on a tripod, but I am unsure if its necessary to do that...

On the 12-100 (and the 300/4), the lens IS switch switches off ALL stabilisation (lens and IS). I can't really see the point - maybe on a very solid tripod?

Re: Oly 12-100 IS switch.

Many people, including many camera manuals, say to turn off IS when the camera is on a tripod. No sense risking the camera moving the sensor around when the camera shouldn't be moving anyway. I usually follow this rule, although I've never noticed a problem when I forgot to.

A better case is when shooting objects moving very quickly, IS can't help - you need a short shutter speed to freeze the action. Since IS takes time to settle the image, some users report that they get noticably better results turning IS off in this situation.

Sorry for being a bit thick but with the 12-100pro and the E-M1ii, if you have both lens and IBIS on you get enhanced stabilisation don't you?

I've just tried mine and turning the lens IS off seems to make no difference, the stabilisation stays the same.

Re: Oly 12-100 IS switch.

Perhaps you have a very steady hand.....

Try two 4 second exposures with IS on and off. See if you tell a difference then. However I think Bassman51 hit the nail on the head. Fast BIFs really don't need IS, and perhaps exposures of over 1/1000 sec too.

Re: Oly 12-100 IS switch.

I have "Dual IS" switched on all the time with the camera in iAuto mode.

As soon as I go in the studio, it all gets switched off as 95% is shot with flash.

I tend to think of lens IS working best on long lenses as the main issue is with vertical pitch movement. With short lenses, IBIS seems the most effective to counter all the other movements of hand held shooting.

On my 300mm f4, if I turn the lens stabilisation switch off it changes the info on the SCP to 'S-IS Off'. The image in the viewfinder is also noticeably a lot less stable.

Re: Oly 12-100 IS switch.

So to summarise then....thus far.

With the IS switch 'ON' the 300mm f4 gives enhanced stabilisation but the 12-100 f4 does not.

Maybe it would be clearer if you use the Olympus term for their 'dual IS' being "Sync IS" since Panasonic call theirs "Dual IS" with neither being compatible with the other.

Re: Oly 12-100 IS switch.

My only issue with the 12-100 is that I sometimes knock the switch on the lens in my camera bag by accident and turn off all IS when I didn't intend to.
