R5, IS on or off for flight shots?

My R5 is tack sharp with stationary birds using 100-500 lens. But in flight shots are in focus  and camera does not seen to struggle tracking, but not tack sharp. Shutter speeds are up at 2500/3200 IS I have tried on mode one and two. I will try turning IS off next time, but not likely to be until next weekend.

Anyone noticed any issues or have any suggestions

i don't own and haven't seen that lens, but as with many canon super-zooms it should have 3 IS modes, of which the 3rd is supposed to be suited for erratic subject tracking, do keep in mind though that the evf won't be as stable in this mode, if you'll be panning on a monopod mode 2 should be fine too (it's the same as mode 3 just for 1 axis movement).

Mode 1 should be avoided when shooting BIF with the RF 100-500, unlike the EF 100-400 II for example. In both cases mode 1 is for static, mode 2 for panning, but the RF lens seems to freeze the shot in mode 1 rather than the usual 2 axis stabilisation of the EF lens.

When I started using the RF 100-500 for shooting civil planes I started off with mode 1 as I was used to with the EF 100-400 II. Almost all of the pics came out blurry, untill switching to mode 2. Things are perfect since. The old EF lens could handle both mode 1 and 2 for the same situation, so behaviour is a bit different.

So, mode 2 or 3 for panning. I would have deactivated IS when using shutter speeds as fast as you say. Anything clearly above 1/focal length normally does not need IS.

I use 1/4000 sec and Stab Mode 3 for BIF. I got many unsharp frames at 1/2000 sec and Mode 1.

Thanks for the reply's I will try Mode 3 and or IS switched off. On sunny days I will also use faster shutter speeds.

Never tried Mode 3 on any of my lenses, not sure why really, just me thinking it can't start up and work that fast, also no advantage with viewfinder being stabilised. I will try it, perhaps you can teach an old dog new tricks

Turn IS off completely for BIFs.  I always have much higher keeper rates without it, no matter the mode or the shutter speed.

Thanks R2, I will try that when out next.

Would be interesting to know why we have a problem with IS now that I have not noticed with past canon cameras. Can't be lens IS as this has worked in the past so it points to IBIS or the combination of the two. Have you tried any older none stabilised lenses with IBIS on?

Bear in mind though, mode 3 only engages at the moment of exposure. I haven’t used it either so not sure how well it works for bif.

Is does nothing for stabilising anything, but does help to stabilise the EVF, when trying to take pictures, using very long lenses. You still have to use high shutter speeds to take sharp pictures. using such lenses

I’ve always turned IS off when shooting BIFs.  I’ve gotten better keeper rates with every body I’ve used that way.

Can't be lens IS as this has worked in the past so it points to IBIS or the combination of the two.

The issue is definitely more prominent with the R5 than with any other body I’ve owned.

Have you tried any older none stabilised lenses with IBIS on?

I still have a venerable EF 400mm f/5.6L, but I haven’t tried it for BIFs with IBIS on.

Canon is aware of the issue and has addressed it through firmware, but IME they still have work to do.

Thanks for all the input.

I only got 15 mins on the bank on my way home, but tried it with IS turned off. Very quick fix, some perfect results.

Try mode 3 if handholding and chasing birds...
