No way of disabling the warning message when powering EOS R off?


I post too Much on Here!!

A Sony... or EOS RP? How about an M6?

You are not making any sense. My point is I DONT WANT THE SENSOR EXPOSED. That's THE EXACT POINT I'M MAKING. If the sensor was covered immediately when powered off rather than a 3 second delay, that would protect the sensor FASTER. It's like I'm talking to a wall here. I will not respond further.
We get your point, it’s just that the people replying to you in this thread either don’t want to turn off sensor cleaning, aren’t bothered by a short delay, or both.

Probably best for you not to respond further. You could try banging your head against a wall instead of talking to one. Or better yet, complain to Canon. On second thought, banging your head against a wall may be more effective.

Hi Folks.
Just to throw my thought out there, I kind of get this.
Does it have some thing driven by a motor and acme lead screw that could chop your finger off slowly if you put it in there?(Approaching the tech of a sluice gate, designed to close a door slowly against the pressure of tons of water!)
If I stick my 1DsIII or 40D (first generation canon live view DSLR with the exception of the highly specialised 20Da) in live view the second I start to turn the lens to remove it the shutter and mirror close instantly, you could not get a lens off before they are closed, is this not the case for the R? Why not?
Seems to me that instant closure has been possible for many years (since 2007) why not use it?

Cheers, Graham.

Um, I severely doubt anybody is getting a finger chopped off by a shutter. ;)

I think if you put your finger in the way of a shutter when it wants to close, you will need a new shutter, not a new finger.

As far as the operation of DSLRs, I agree that it is strange that DSLRs immediately clamp down the shutter and mirror when you remove a lens, but not the EOS R. I can only assume it's something fundamental within the firmware.
This only happens with adapted lenses. The message doesn't appear when using RF lenses.

The reason, I believe, is because RF lenses stop the aperture down to maximum aperture when switching the camera off, whereas EF lenses don't. They stay at minimum aperture.

ist that 3sec for closing image stabilation on lens rather than protecting sensor?
