Regarding new M11 2.0.2 firmware dust protection function feature.

Hello,

I just want to clarify.  Regarding the dust protection function in the new M11 2.0.2 firmware update.

Should that function be kept in the on position or turned on only when a lens change takes place.

This is what is stated:

"The dust protection function can now be activated manually for lens changes."

Thanks for your help.  I know I'm being overly cautious.

In general, it's good idea to keep it in the always on position. In case you forget to turn off the camera when switching lenses, it will automatically close the shutter (when the lens leaves the camera body) to prevent dust from entering the CMOS sensor.

There are cases where you could turn the dust protection function off to suit your usage:

Situation 1: When using a lens adapter that the camera won't recognize, the shutter closes automatically; you can turn the function off for continued use.

Situation 2: When manually cleaning the CMOS sensor, and you want to expose the sensor for cleaning, turning the function off might be helpful for the cleaning process.

The wording from Leica is a little unclear... it is a set and forget feature, depending on personal preference. 

If dust protection is set to On, then every time the camera "thinks" or "detects" a no lens situation, it will close the shutter. This can be spoofed, and some M39 adapters can set the shutter to close because the camera thinks no lens is attached. Also, when a lens is detached, and the shutter is closed, an environmental change in light brightness can cause the camera to open the shutter again even with no lens attached. For me, this easily happened when changing lenses indoors, and I happen to move the camera a little while changing lenses. A bright light of a distant window would make the shutter open and then close. 

Personally, this feature is best kept off. It's more reliable to just switch the camera off before lens changes.

Indeed, it's a characteristic that pushes the M further into a realm where the camera assumes control from the user.

- entering rant mode - The next step might involve a battery compartment that only "unlocks" when the camera is turned off, preventing the removal of the battery or memory card while the camera is still on. Am I alone in desiring control; that's the allure of the M. We certainly don't need poorly executed new software features that, just weeks after their introduction, already require fixes because the software developers were detached from the camera's actual field use (such as with non-coded lenses or M39 adapters). What is wrong with the straightforward advice to "switch off the camera before changing the lens" and leave the rest to the user? Do we truly require a nanny that tries to anticipate our needs?  If Leica genuinely believes a user can't survive without this feature, then the design of the SL2, for instance, must be seriously flawed, considering that even with the camera switched off, the shutter stubbornly insists on staying open. Oh, the unbearable risk that Leica SL2 users must endure! - rant mode off.

Leica was listening to users begging for a closed shudder when changing lenses. Well, here it is.

I don't care either way, I do routine cleaning anyway.

But to your question: the on-off button is for the function to be active or not. the option is there to turn it off for some use cases because some older lenses and off-brand adapters don't cover the 6bit coding reader and can result in unwanted closing of the shutter. For does people the OFF option is probably better.

After reading these comments I’m more convinced that I don’t need 2.0.2

Since day one of 2.0.1 was released I said this shutter close function is utmost useless function

Dust protection can be kept in the on position when using coded lenses. Better turning it off when mounting uncoded lenses though. Otherwise, the camera may fail to recognize the lens and the shutter could remain closed accordingly. Easy to do through a user profile if needed.

Thanks for all your help and info (including the rant. 😀

I believe I'll just turn the camera off for a lens change.

If I understood this, the shutter is closed when the camera is off.

allow me to rant again.
If you keep the shutter protection function off and just turn off the camera every time you change the lens (like normal people usually do), what does 2.0.2 do good for you that 1.6.2 cannot?

[jdlaing]

Dust protection. 
 

Shutter closes. You remove the lens. Dust enters the throat of the camera and waits patiently. You mount lens. Shutter opens. Dust is still inside.

Brilliant idea.

• Can combine self timer with other operating modes
• Tethering support
• Assign the first three characters of file names
• Improved Leica FOTOS performance
• Unlisted firmware bug fixes for bugs that were in 1.6.1
• Listed firmware bug fixes for bugs that were in 2.0.1

I can now more reliable use the camera with FOTOS for geolocation metadata.  I use the ability to change the image file name prefix.  I've not run into any new issues with the newer firmware. For me all is good.

If you don't have any issues with 1.6.1 and don't care about any of the changes then not updating may be good for you.  There is no right or wrong answer.

I never use foto to tether or update firmware. I just occasionally use it to transfer the jpg to the phone. Even that it’s as rare as one out of thousand pictures odd.

I never care about the file names.

“unlisted bug fixes” means you don’t even know what they did if they did anything.

I never went with 2.0.1, so last point of “listed bugs” is invalid to me.

To be honest my suggestion is none of m11 owners should update to 2.0.1 or 2.0.2, it’s the most useless firmware so far. And I’m sure whoever did that is in a rabbit hole now because you will see 2.0.3, .4, .5….. endless coming to fix so-called unlisted or listed bugs.

2.0.1 came out for m11p, we m11 users are just guinea pigs. Leica made this half baked 2.0.x available to m11 owners to just patronize them. This is just a lamé game to make m11 users feel they are not forgotten

I’m waiting for 4.0 maybe couple of years down the road if I have sold m11 before then

In your previous response you should have phrased it as me rather than you. It has some benefits for others but not you.

Different experience here. I could not use some of my uncoded LTM to M adapters in the past, due to the shutter being closed by the dust protection function. Now i just toggle off dust protection for some uncoded lenses and/or adapters, while keeping it on for coded lenses and adapters at will. Easy to do through user profiles if needed. One of my user profiles was dedicated to uncoded lenses since i got the camera actually so i simply had to update that very profile by setting dust protection to off, that's all. FWIW

Umm useless to you. Not useless to a lot of people. 

For ME, the Fotos app is stellar and I use it all the time. For landscape, the uncoupling of the timer mode with other operating modes is really useful. 

Seems to be a lot of complaining about nothing...

I am not the one who is complaining because I am using 1.6.1

The people who updated to 2.0.1/2 are the ones whining loudly.

Don't count me in please, those recurrent complaints are becoming boresome, especially when they are based on gratuitous or disputable statements.

The people?  I believe a more accurate statement is "some people".  I haven't a clue as to the number of people in that category.  Speaking for myself (and only myself) updating to 2.0.1 and 2.0.2 were non-issues that gave me some added functionality in the "nice to have" category.  I understand that you don't want/need the added functions.  Fine.  Don't update.  Your choice.
