how to find out shutter actuation for M digital?

Is the link below being the correct / reliable way?

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

That works for the M8 and M9. But not later M digitals.

Once video and live-view were added with the M(typ 240) and later CMOS cameras, it is no longer a reliable method. Reason being that the shutter can be actuated many times for live-view - without actually producing a picture file with a unique image ID to test.

Important point of logic and language. All M9s are M digitals, but not all M digitals are M9s.

It’s also possible to use the rear controls of an M8 or M9 to extract shutter counts.  
 

For M8....

For M9..,.

Just to add- On the M8 using the "button dance", the "DEBUG" mode ends once the power is turned off.

 

I did the M9 button dance once time: I had to reload the Firmware using the standard procedure of copying it to the SD card to get the camera back to normal mode. The difference- the "bad pixel Mapping" stopped working in Debug mode. That was with an older version of firmware, 1.174. I've not tried it since.

I had zero issues to use buttons with my M-E 220. This was before latest firmware.

The M262s don't have live view and the M-D and M10-D do not even have a screen but still they're lacking the count information in the files 😜

So, how do we retrieve the shutter count from newer Ms?

You don’t.

Apparently, maybe you can, via this software: https://transienteye.com/software/

Mentioned in this thread:

BTW - that thread mentions that the Leica unique Picture IDs are now hashed - converted to a number of constant length that only means anything to a computer with an appropriate look-up table and function to decode it. The software mentioned provides the decoder, it seems.

https://en.wikipedia.org/wiki/Hash_function

But it is still only a count of pictures taken, and will only reflect shutter actuations (approximately) if one never uses video, live-view - OR an EVF (M10-D), which is just live-view via a different viewing screen.

Leica's firmware writers do not consider it an important feature that users can read their own shutter counts easily.
