Re: AF miss / shake / shock?

Heads up, I'm seeing a relatively high rate of shutter shock / AF miss / IS gyro shift on my continuous bursts... I also saw this on the M6 Mark II, but, at 14FPS, picking the sharpest wasn't a big deal other than processing power / time needed to do so.

I've ratcheted back up to high speed FPS and C-RAW to help mitigate and will re-attempt. This is with continuous AF off.

Thoughts on culprit? Folks around here assumed it was shutter shock / M6 Mark II. I'm seeing it on the M50 Mark II.

I didn't see it on my time with the M50 Mark I, but, then again, I wasn't using continuous drive / AI-servo so heavily. Well I was, but maybe I've gotten more picky? Might have to go back to the archives but the problem wasn't this, problematic. I also wasn't using the 15-45 though heavily back then either. Could be a 15-45 idiosyncrasy where the STM motor is catching up?
Not sure the problem here
nothing sharp in photo
were you using eye servo? my guess is either 1) you moved or 2) the eye focus was skipping off the eyes because the eye's are not pointed at you
with m6II, unless the eyes are pointed at me, I'll use spot focus
After
ahh, now the eye is pointed at you -- bingo
IS-motor sync?
slow shutter speed and no good focus point -- are you still in eye focus mode? I'd not drag the shutter when you have enough light. Get it up to at least ss 1/125
on M6II -- I'd be using spot focus and looking for a contrasty edge
After
AF shift, obvious back focus
speed up ss -- also you have competing subjects in the frame if you are still in eye focus
Correct focus, after
Whatever the case may be, I'll say the M6 Mark II with it's larger buffer, higher FPS capability, was easier to mitigate IS-motor syncs, AF shifts and critical focus / subject movement issues. I just prefer it was the M50-DSLR body type...
for people, suggest not dragging the shutter down to ss 1/60 or ss 1/80
for people facing you then the eye focus should be ok. When people are not facing you (like first shot) , switch to spot focus
just some thoughts
BTW, my EOS R doesn't share these hiccups. Yes, the lowly, original R.
