M11 lacks dust detection feature

This is an observation, not a complaint.  Previous digital M cameras had a dust detection feature, but not the M11.

While this feature was available on the M10-R, I never got it to work, and I tried many times.  I would always receive an "Image inhomogeneous" message.

My guess is that Leica has decided that this function will not work on high-resolution sensors.

Perhaps, but I suspect, given many folks complained about the image inhomogeneous message, that they decided there was no need to formalize the process and cause consternation.  It's pretty easy to stop down, shoot a blank wall and note the presence of any spots.  I'm actually a little surprised they bothered to leave in the sensor cleaning mode at all given all one need do is be in LV and the sensor is exposed for cleaning anyway.

Using Sensor Cleaning prevents accidental closing of the shutter (shutter release, timeout, or power switch).

are you sure it was a dust detection function or are you talking about the cleaning function which would open the shutter for access to the sensor?

if so - you wouldnt need it with the M11, because the shutter opens as soon as you switch the M11 on.

As I wrote above, using the sensor cleaning function prevents accidentally closing the shutter (time-out, shutter release, on/off button) and thus damaging it while wet-cleaning the sensor. 
I suggest using it when cleaning the sensor, as it may save you from a costly mistake.

[Hey You]

The sensor cleaning function still exists.  Go to "Camera Settings" and scroll down to "Sensor cleaning."

This function prevents the shutter from closing inadvertently while you are in cleaning mode.

IMO, OP was pretty clear that he refers to the Dust Detection functionality (not Sensor Cleaning) available in M10 cameras but removed in M11.

ok, sorry. I didn't remember this function existed. my fault.

In my experience (now 5 years with the M10) the dust detection mode has worked well on both the M10 and M10-M as long as a 50mm or longer lens is mounted.  It the non homogenous message comes up when a 35mm or wider lens is mounted.

Don't you want dust and scratches? It give you a more analog feel.

"Image inhomogeneous"

I would get that message occasionally from my M-P 240.  I would just go photograph a "homogeneous" surface and was then able to use dust detection before cleaning the sensor.

I do hope they manage to bring back the feature in another model. Perhaps it needs a faster processor to work as well as it did on the 24mp cameras. I loved being able to see where my spots were right on the back of the camera. Made cleaning quite fast.

I prefer using a sensor loupe to invoking Dust Detection operation.

It happens with my 50mm Summilux, 90mm summicron and voigtlander 28mm ultron 2. The only solution I found was using a white reflector on a good lighting condition for that fonctionality to work.

I generally open a new blank E Mail on my Mac and set the brightness to max.  No issues with this a method using the 50 Summilux or 75 Summicron.
