Switching the camera on and off for several times and the reaction times of the curtain..

Last night I switched off and switched on the camera several times and I noticed that the camera does not open the curtain as quick as the first time I switched it on.. it takes like 3 or 4 seconds to open it.. but when I switch it off and wait for a few seconds  and turn on again, it reacts as expected..  Does anyone experience this situation before? Or is it normal?

Why does this matter?  Not trying to be rude, but seems like such and odd use case for the camera?

Well of course it is not very important but it seemed quite not responsive like M10 .. I’ll record a video and you’ll understand what I mean..

There is some sort of startup check it does when the camera has been off for some time. Not sure what the purpose of the delay at startup is, but it's probably similar to how sometimes at shutdown it takes longer for the camera to turn off while it does a hot pixel/dead pixel scan.

you are getting consistent results from your test based on how long its been since you last turned on the camera so im going to say this is normal behavior.

I haven't tested my M11 but my gut tells me your camera is ok

I noticed this exactly same behaviour on the first day when I got camera.

I don't bother to care though.

Happened to me, when it on and off in succession, there’s a time in between where it takes longer for the shutter to open, hence the delay, thought at first it was due to the sdcard reading, and now most likely im wrong

I hardly find this surprising. There's a computer in there. When you throw the switch you're not physically disconnecting power, you're generating a signal that the software detects to initiate a shutdown sequence. The system presumably has to check a number of things, for example the image buffer is clear with all images written, before it cuts power.  I.E. shutdown is not instantaneous. Throw the switch rapidly on/off/on/off and the software might not even notice some of the transitions as its already in a shutdown sequence.

I made a bet with myself that if I duplicated this, the rear LED would be lit up. And indeed, exactly as I suspected, switch on and off a half dozen or so times and the red LED remained on for several seconds with the camera 'hung'.   The LED signals the camera is busy and will get on with things as soon as it completes whatever it happens to be doing.  Eventually after a few seconds once you stop toggling, it goes out and the shutter click finally can be heard.  On one occasion things did a little confused.  I rapidly switched on/off ending in the off position, and the camera remained on, the rear display lit up with the battery indicator showing a empty battery.  Weird... particularly as I had the V2 attached...  I just turned the camera off and it came back up battery full, camera fine.  

While this little quirk is interesting for what it tells us about the camera internals, otherwise, its not worth worrying about.  The OP's camera is functioning normally.

Quicker power-ons right after a power-off may also be taking advantage of residual energy still in the camera.

yeah i wouldn't worry it too.. hence i never take that into account and thanks for pointing out the LED lit up i should have mentioned earlier and that's also the reason why i feel oke

even the fastest apple silicon have some days off too 

i just thought at first it was a slow response or some sort from the sdcard but now i can write that off

Indeed. A brief parable on that subject.

Recently, my few months old MB pro stopped charging... but only from the right thunderbolt port. The left ones and the mag charger worked fine, but the right was dead. Hooked up an external ssd to verify the port wasn't working at all and indeed the right port doesn't see the drive, but the left ports do.  Naturally, I assume some form of hardware fault, bad chip, broken connector, what have you. So, I take it into the genius (really?!?) bar assuming I'm going to need a replacement. They confirm the issue and take the computer into the back to check it out further.  Five minutes later the genius returns...

"Fixed", says he.

"Really?" says I. 

"Yep" says he. 

"How?" says I. 

"Reboot" says he.

Dumbfounded, I checked the port was working again, and indeed it was.  Once home I realized that Apple recently introduced this new battery charging strategy that limits the recharging to 80% under some circumstances to extend the lifetime of the battery. They must, therefore, have a software thread that monitors the charge level along with the ability to switch off the port to stop the charging.  Presumably the thread responsible for this either died or got out of sync with the port state.  Had this happen for the second time just the other day, rebooted and everything was good.

So yeah, all these systems have quirky little issues which at first glance you might think represents a hardware fault, but in reality are just the result of software flaws.
