Sensor Cleaning Menu...Dust Detection not Working

[david strachan]

I've previously used the Dust Detection, but now greyed out and not working.

I've reset my M-P, used a fresh charged battery...but still no luck.

 

Can't find anything in the manual.

up to date OS 2.0.3.0.

Tried various file recordings, eg DNG, DNG+JPG, etc.

 

Sensor Cleaning opens the shutter.

 

But no luck getting the Dust Detection to work.

 

Any help greatly appreciated...thanks.

On my M the menu item is active and working when there is a lens mounted; it's greyed out when there isn't. This sounds reasonable as the dust detection program analyses a picture taken with a small aperture.

Hi David,

I had the same problem that I've reported here at the time.
When I upgraded the firmware (I have the penultimate firmware update), that issue is over.

Sorry my English

Thanks Pop.  Yes have been trying with a lens on the camera.

Thank you joao...I've reinstalled the 2.0.3.0 firmware, but still greyed out.

 

Can't really think of any other fiddles to try.

 

I know some would think it is just an "extra" not necessary to the photography, but I quite like it, and would like my camera working perfectly also.

 

Any other thoughts gratefully received.

 

cheers..

The lens has been detected? Otherwise, try a factory reset (in the menu).

[david strachan]

Thanks Exodies. Did the reset.

 

It's solved...

Seems my ltm lenses with M adapters don't work for Dust Detection.

Hint was from Pop..thanks mate!

 

I tried one of my few M mount lenses...90mm-C...and Dust Detection worked...yea!

For some reason the cut-outs on the adapters signal no lens perhaps.

When i get home I'll try some other adapters. But good to know it is a hardware problem...glitch.

 

Like all of us we want "perfect working order".

 

Thanks everyone for your help.

 

Cheers...

LTM lens disabled it here too - love this forum - thanks guys!

 

Now about that filthy sensor...

Somewhat related:  I have used the Dust Detection system on my M240 and it works but I don't understand how: does it save an image somewhere that can be filed away and used as a reference point?  If not, exactly how does it work?

It is just an analyzing tool, although I suspect you can use it as a mask in Photoshop. Anyway, I used it only once; far too sensitive.

I'm not sure I follow you:  unless it is saved somewhere, how would you get it into Photoshop?

[Exodies]

You can't. Jaapv was suspecting wrong. You use the spot picture displayed on the camera to drive your cleaning efforts.

Isn't in this case any sky/white wall photo taken at small diaphragm, at 200ISO and exposed correctly

a spot picture?

The reason I'm asking is because I have a one year old pristine bp M-P from the first owner for half the price. Got to love the M10.

Yes, it is. Spot on, as they say.

Pity, it would have been usefdul. You can tell that I never use the feature

[sblutter]

I'm getting over my obsession with a spotless sensor.  I agree with Jaap dust detection is too sensitive and with tri that the more useful method is to capture a picture of a white wall (or totally clear sky) to locate interfering particles (on a big screen computer)

 

Even then its not the biggest deal for me.  Why?  Every image I work on is intended for exhibition sized at least 17x22", meaning I'm going to go over every inch of every image @ 100% looking for flaws to retouch (in PS), be they cigarette butts or sensor dust anyway

 

When its too dirty, get out the kit.  Seems changing lenses, no matter how carefully, mysteriously increases dust accumulation 

[rbaron]

Of some slight interest:  when I first tried to use this 'feature' by aiming at what I thought was a clear blue sky the camera told me it wasn't clear enough (non-homogenous?) and to try again.

 

There's always a critic, isn't there?

After running the dust detection whose swabs, liquid, lens pens do you use? 

 

Eyelead cleaning kit and VSGO swabs were suggested to me. Have used eclipse on other camera in the past.

[rbaron]

I've used Eclipse products for a number of years now.

[Exodies]

Rocket puffer has been sufficient for me so far.

Hallo,

Look here: Leica M

[ru2far2c]

Thanks- I just need some full swabs, they are around here somewhere. Found the liquid.

yes, the rocket puffer works well. Sometimes it needs a little extra help!
