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

TIA, R2

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...
