Don’t need RAWs if you just post some screen shots from DPP (with AF points showing). Do include EXIF tho.

TIA, R2

One more photo:

Thanks for these. I've seen this phenomenon reported here before (here's one of the threads)...

I think the AF algorithms try to paint a happy face on occasion (indicating AF lock when not actually in focus ). The cymbals just seem to be a much better AF target than the face (esp in lower light), even when the cymbals are not under the reported AF square.

There are still occasions esp in low light (IME) where Spot AF produces better accuracy. In fact, I suspect that you will get close to a 100% hit rate under these conditions (vs Face/Eye detect).

ps. I've always suspected that the AF frame designation is actually done post-shot, and is not a real-time indicator of focus. Just a theory...

The thread is indeed this behavior.
I'm not surprised, I'm not shooting in the easiest condition either
I do switch between Spot AF & Tracking, but until now, I was seeing clear hesitation of the AF the the EVF. It's the first time I see this this specific case (and well, this photo was cool).

I love so much my R6, that I tend to forget that it may have limits Hence I'm still learning its limits

The RF 70-200 f/2.8 is known for front focusing at times. And I suspect there may be some aberration/ reflection from that cymbal throwing off the AF. It’s a machine, nothing’s perfect.

This is one area 1DX III shooters have reported better hit rate (reflections/glare vs the R5/6), and I expect the R3 resolves between enhanced algorithms and faster, more sensitive, readout. Sometimes it is the machine to blame.

Most of the focusing reticule is not on the subject so it grabbed the nearest thing with high contrast instead, the cymbal.
