Hi, I own a Leica SL3 with 24-90 and I can't decide what minimum shutter speed to set with IBIS on... what speed do you use?

I always use Aperture priority and let the camera decide which shutter speed and ISO value between 100 and 3200. Depending on which focal length I can do 1/2 to 1/8 of a second as lowest with the 24-90.

I up the ISO each generation. I am fine with the S3 up to 12500. It is a real breakthrough to be able to use this sensitivity.

It really depends on the stability of your hands and slow-speed shooting technique. And remember: IBIS does not compensate for motion blur of your subject. Only molasses will do so.

Personally I dont let the camera choose shutter speed, I tend to opt for Manual with auto ISO, like a semi-manual so to speak.

I often shoot in dim, or post sunset conditions handheld, the best way for this is to set the shutter type to Electronic to avoid any shutter shake at all, theres a definite difference here too. And then set your shutter, depending how steady you are. I would be happy shooting a 35mm at 5th second with electronic shutter. Maybe less in fact.

Every one is different. Do your own tests. Also close and distance will be different. I get to 1/10th F with careful technique and adjust for environmental conditions and coffee drunk, etc. Working out your threshold should take about 15 mins and has other benefits like learning a bit more about your camera and settings.

Use both electronic and normal shutter. My tests show that shorter lenses don’t really have shutter shock issues but that was for me. YMMV,

That is correct. The shuttershock problem manifests itself mainly on lenses over something like 300 mm. IBIS or OIS cannot compensate for it as the frequency of the vibrations is too high for those systems to follow.
