Fix Canon R5 Mark II not honouring the "Shutter at Shutdown" option if Electronic Shutter is chosen.

C-Cella — Thu, 02 Oct 2025 08:48:27 GMT

For the Canon R5 Mark 2 it is possible to set the "Shutter at Shutdown" to either "Closed" or "Open".
This option is NOT honoured when Electronic Shutter is used (ES)

The camera offers 2 ways to "shutdown".

1. Power Off : camera is off BUT can be awakened in this state by half pressing shutter or pressing other buttons.

2. Shutdown using the "Power/multi-function lock switch".
In this case the camera can't be awakened by half pressing shutter or pressing other buttons.

If the camera is in Shutdown (2) the "Shutter at shutdown" option should be honoured even if the user has chosen ES.

This can no doubt be fixed via firmware.

My R5II (firmware 1.1.1) works like this(open when set open, closed when set closed, ES, power switch off) so depending on your firmware version it's already fixed or it's something else.

I am on the latest firmware.

When Electronic Shutter (ES) is chosen the "Shutter at Shutdown" is not active the shutter always stays open.

This I believe was done by Canon to ensure that when the camera is "Powered Off" not using the "Power/multi-function lock switch" (we could call this state "Sleeping") the user can awaken it and resume shooting operation with shutter alredy open.

When the camera has been shutdown using the "Power/multi-function lock switch" the awakening is not possible and thus in this case "Shutter at Shutdown" should be allowed to be "Closed".

Typical use scénario (if Canon fix this)

1. User is using ES

2. User shutdowns the camera using "Power/multi-function lock switch".

Result : Shutter is closed, sensor protected from dust, user can change lens safely.

Currently what Canon requires us to do is the following:

1. User is using ES

2. User must switch to Mechanical Shutter.

3. Shutdown camera via "Power/multi-function lock switch" or Power off (Sleeping)

4. Shutter is closed, sensor protected from dust, user can change lens safely.

5. Power On and set ES again.

Not sensible, is a waste of our time.

But my R5II works like your first scenario or I'm not understanding you. If I have set shutter at shutdown to closed, this is what happens:

1.I use ES

2. shut down using power switch

3. if I remove lens I can see shutter is closed

If I set shutter at shutdown to open it's open when I remove lens.

Check if you are using Electronic Shutter- 1st Curtain

In that case since the second shutter is mechanical upon shutdown the shutter will indeed be "Closed"

(I checked again and I am on Firmware 1.1.1 for both R52 and Canon Ring Adapter)

You are describing the correct behavior, except for one small detail. When the camera goes to Sleep Mode it doesn’t turn itself off.

This is is full ES, not ESFC.

You are nitpicking.

The camera itself offers to "Power Off" (command can be assigned to buttons via: Customise buttons for shooting *)

I am using Canon terminology here.

In this "Power Off" state the camera can be awakened (Canon should have called it sleeping but didn't)

As a user I am not satisfied by the behavior of the "Shutter at Shutdown" option when using ES and shutting down using the "Power/multi-function lock switch"

Makes little sense to me.

As I described it forces us to switch to "Mechanical Shutter".

Seems you don't believe me but as mine behaves in the way you desire it's not something Canon can or has to change. Either you have a setting wrong or your camera has a malfunction.

Sleep Mode means Stand-By. If the camera were actually turned off, then pressing the shutter would not wake it up. Obviously, because the power switch is still in the ON position.

Looks like we are going to have to agree to disagree again. Have a great day.

@pcs1

I was not doubting you.

Then my brand new camera is malfunctioning because if I set ES the shutter is Open at Shutdown.

I now see what's happening.

I have set "Silent Shutter Function : On" even in ES and this makes the Shutter at Shutdown always be Open.

I was so focuses on the shutter type I didn't look at the other options.

Huge moment of stupidly on my part.

But you did find it, I hadn't thought about that one, all I could think it must be a setting.

Yes but still stupid me.

Perhaps at Shutdown via "Power/multi-function lock switch" the shutter should be "Closed".
Else when camera is in "Standby" a.k.a. "Sleeping" a.k.a."Power Off (not Shutdown)" the shutter would stay "Open".
