I saw on Whistling wings photography video that it is necessary to pay more attention to the stabilizer mode on the 100-500 than the 100-400.
I have been checking the focusing using all three modes and found that on mode 1 when focusing on a still subject the spot focus point becomes so stable it is unmoving. This is hand held. Then on mode two it moves around a little even when I try to hold it absolutely still. again on a still subject. on mode three it moves a lot more and is impossible to hold stable before taking the shot. I have not tested if this means that the shots are more in focus in mode one on a stable subject but probably. I take birds in flight a lot and am using mode two for that as it is mostly panning.
In mode two I also take birds that are still and it seems ok but maybe I should move to mode one for still birds.
Also I am going on a pelagic trip shortly where the movement is all over the place up down and sideways so will try mode three for that.

Also After the 1.1.2 update on the R5 I think maybe the 100-500 is sharper. maybe immagination! ...Show more →
Yes the R5/6 with IBIS seem to make the lens IS mode much more important. I don't think it is a 100-500 thing, more an IBIS/IS interaction thing. An adapted 100-400II would need to have IS managed more than on a DSLR.
IS 3 does not stabilize the image until the moment you take the shot so you see how shaky you really are.
IS 2 only does stabilization in the single direction at a time depending on if you are moving the lens up and down or side to side in a panning movement.
IS 1 is best for still subjects to just maximize IS at slower SS for any perched bird.
IS OFF is probably best once at 1/1600 or faster (maybe even at 1/1000 or so).
On DSLRs I left lens IS at Mode 1 all the time. With the R5 I'm usually using IS 1 or IS OFF. Canon still has work to do with IBIS/IS integration in my opinion...it seems fairly Beta to me so far.
I leave it on mode 2 pretty much all of the time on all of my lenses for perched as well as bif. Mode 3 is too difficult to use and I just forget to switch to mode 1 for static subjects. It stays on with long lenses for birds/wildlife and is off for short lenses for landscapes. I haven’t noticed a difference at faster Tv unlike some of my dslrs.

What about shooting on a tripod? Should IS be turned off? What does Canon recommend?
Modem lenses sense no movement and will stop stabilizing automatically. I had to turn the IS off with my 300 F4 IS because it was first generation IS. One reason to shut the IS off is to save on battery power but that is different now.
With RF lenses IS runs even if you turn it off. I tested my RF 24-105 and it makes the same sound with the switch on or off. If the switch is off it is still engaged, it just doesn’t stabilize. It only shuts off when the the power savings kicks in or you shut the camera off. The IS assembly has been redesigned for RF lenses. So turning the IS off probably won’t make much difference.

Just to note Mode 3 works the same way as mode 2 when it kicks in.
I have always used IS in the last 15 years. This R5 IS thing has me a little perplexed. I got my 100-500 before my R5. I was nailing BIF with it. By the time I got my R5 in September an event prevented from getting out much. The few times I did it didn’t go well. I have not had a chance to try with IS off because there isn’t much flying around this time of year. It will be a while before I get to do some testing.
45 megapixels is a new ball game for me. As pointed out in other threads increasing SS and paying more attention to technique just might be the answer.

Usually, a combination of issues are in play. First, 45 MP are more demanding though I've found it to be extremely manageable. The 100-500 had some problems initially with the IS interfacing with the camera which was addressed in subsequent firmware updates. Personally, I've found the IBIS/OSS to be very effective under a variety of circumstances from fixed objects, to sports, to BIF and with all lenses tested. Quite frankly, I've found it to be the best, i.e. most effective and stable of any Canon product to date. As I mentioned, mode 3 I don't use because there is no stabilization in the EVF until the shutter is pressed. As a general rule, mode 2 works great on/off the tripod for BIF as long as one is panning in the horizontal plane. The few perplexing oof shots have always been tracking birds flying towards me overhead as I am panning more vertically. I haven't tried mode 1 under those circumstances (it corrects for both vertical and horizontal movement) and when I've remembered to use mode 1 on static subjects, it has worked well. The Tv issue is a bit of a misnomer and I've used speeds comparable to my dslrs.
