R5 IBIS delay before 100% stabilization?

[RickHberg]

Curious if others have the same experience. If I handhold the R5 with IBIS on, and just focus on a static object, it takes around 3-5 seconds to get really good stabilization.

It looks like some stabilization prior to that, but with some floating. So I assume it's just running through an algorithm in that time to obtain the super good stabilization. It's only an issue sometimes with subjects like small birds that hop around on branches and don't sit still too long.

I tried on RF 100-500, EF 100-400, and an EF 24-70. All had similar delay until the really good lock. Thanks for any insight to your experiences with IBIS!

Have you upgraded to all latest firmware? I just installed 1.5 on my R6 and it is now AWESOME!

[RickHberg]

Yes I have firmware 1.5.2 installed. There is still the 3 to 5 second "floating" or searching before full stabilization on my R5. Are you saying that you used to have this experience on the R6 but now it is gone after the firmware update?

Did you ever find a resolution? I have this issue on my R7 and EF 100-400 MKII.

[RickHberg]

Unfortunately no. I think it's just normal operation for Canon. It's pretty annoying with fast, brief subjects like small birds that are gone 3 seconds after showing up, but I've gotten used to it. Or at least, I accept it I guess. I still get great photos, but much fewer keepers in the first 4 seconds

I suspect you are 100% correct. I went to National Camera Exchange this afternoon and tested their copy of the RF 100-500. It had the same delay of 3 seconds that my EF 100-400 MKii has. Seeing how one is RF and one is an adapted EF lens, I was able to rule out the lens as the cause of the issue.

I then tried their copy of the Canon R7 against mine. I used all my normal settings that I use for wildlife photography, and theirs I factory reset. The only changes I made to theirs was enabling tracking and Servo AF. Both bodies had different firmwares, my copy is up to date, while their display model is 4 versions out of date. I used my copy of the EF 100-400 MKii on both bodies.

Both bodies had the same delay of 3 seconds. This seems to indicate that it is just how Canon bodies handle the IS.

I have read that IBIS is not used with EF lenses that have built-in IS.
