IBIS and OIS

On an SL body, all this does is switch the IS system from the lens to the body, so IS would still be active, just in another way. You’d also need to turn the IS off in the body (while the lens IS is off or the option is greyed out). The system would still use some power to keep the sensor floating.

I am not sure how much more power the lens IS uses compared to IBIS.

In my experience with Nikon long lenses, OIS on lenses with heavy glass drains battery a lot. IBIS  drains much less battery than EVF or LCD.

@FlashGordonPhotography, my experience aligns with this above. I'm ok with IBIS reactivating when I turn off OIS, I just don't want OIS running constantly sometimes, especially with lenses with large elements that draw a lot of power to stabilize. If that 105mm filter on the end of the 60-600 is any clue to the size of the elements in the stabilization group, then it's probably drawing a lot of power with OIS on 😵‍💫

That said, I wonder if the IBIS of the SL2/3 actually reactivates when the Sigma OIS switch is turned off. I don't have a stabilized Sigma lens at the moment to test it with (still need to re-buy some L lenses after bouncing back and forth between M and SL systems a few times).

With lenses of the focal lengths we are discussing, it should not make much of a difference whether IBIS is switched on .

I prefer the way I can set up my Nikon: the shutter half-press enables stabilization.

The problem being however, that when you are in a situation that requires quick reactions, this will lose you opportunities. I find a battery grip a better solution.

Yes it does, up to about 400mm which I think is the limit of the SL2/3 IBIS. I have a flock of Sigma lenses in L mount. When I did my shutter shock testing on the SL3 I had to test with both IS systems on/off as well as mechanical vs ES.

I’m more than happy to go with you and SrMi on this. I have the lenses but have never bothered to test for extra battery drain. I do trust your experiences will both be accurate.

Agree.

Sigma lens switch is a workaround. Definitely not ideal. That's why I originally said I wish we could have the option for stabilization only to be active half shutter press like the S5IIX (and others) 😁

Could be interesting to test generally (an hour shooting with just IBIS versus an hour shooting with just OIS – but it would be hard to keep it equal). Perhaps OIS is more efficient than one would think.

More like a matter of preference . I prefer lens switches in general. Much faster and ergonomic in use. No delving into menus or wasting Fn buttons for occasional functions. And I like the USB programmable function switch of some Sigma lenses.

I like one way of doing it. I find it confusing when sometimes you have to do it on the lens and sometimes in the camera.

I like to avoid doing things on the LCD other than setting up the camera.

That would mean avoiding all Leica L-mount lenses.

If truth be told - it is one reason that I prefer the Sigmas over the parallel Leica versions

And similarly, truth be told, that is why I prefer the Leica versions to the corresponding Sigma lenses. We are lucky that we have a choice.
