SL2 - Safe To Leave IBIS On w/ Tripod Use?

If it’s only using accelerometers then mounting it on a tripod should be ok. If it’s not monitoring the image then the only alternative I can think of is a bug.

It is conceivable that when on a tripod, the accelerometers read enough noise to fool the stabilization algorithm into stabilizing something that does not need to be stabilized.

It is conceivably, too, that the correct explanation is something completely different.

Yes, except the noise will be present when handheld too.

It would be very helpful, if someone with some clout with Leica (e.g. the Administrator) could prod Leica to give a concise and practical answer to this question. Speculation on the basis of unsubstantiated assumptions gets us nowhere. Leica ows us an answer; after all, we have paid for the stabilization device.

I was specifically told by the Panasonic rep at the S1/S1R launch that leaving IBIS on when using a tripod was beneficial as it reduced micro-vibrations .... which is entirely logical, if the accelerometers are accurate and sufficiently sensitive. Quite how inappropriate compensation is generated when the camera is still rather eludes me ..... and also I can hold the camera still enough to take 100% sharp images without IBIS at plenty of slowish shutter speeds, so should I be switching it off then as well ? Unless there is more going on here that I am not aware of the blanket 'switch it off' advice is illogical.

I leave it on all the time. Prior to the SL I've never bought an image stabilising lens because I didn't like the outcomes. But since using the SL and the SL2, it's been a positive so far. Sometimes my tripod needs to be at extremes so stability isn't great, the IBIS works great even at 1-2 seconds.

Perhaps people’s experiences in the comments here might vary depending on typical shutter speeds. Personally Iong exposures (even a second or more) aren’t part of my photography. More like normal 1/125 or faster or even just syncing with flash.

So I will qualify my reported experience by saying at typical handheld speeds ( while on a tripod), I haven’t noticed any difference in results with Stabilisation off or on. The tripod gives me much more consistency in framing including level.

Obviously, those situations are very different to some landscape or night sky type styles

Looking, nothing in the SL2 manual says to turn it off while on the tripod whereas in. previous cameras with IBIS, Pentax, it specifically stated to do so.
