Cleaning the SL sensor

Recommended Posts

Advertisement (gone after registration)

Love the camera, but the manual is ofen next to useless. I can't seem to find anything about the sensor cleaning system in the Leica SL.

 

Can any of you advise on the following:

 

1) How does the electronic sensor cleaning system work? Does it activate on startup/shutdown as it does on my Canon SLR, or does it have to activated manually?  If the latter, where is the switch in the menu structure?

 

2) Is there a specific procedure to follow for manual cleaning of the sensor?

 

3) Is there a dust detection system similar to the one in the M cameras?

 

Thanks.

1-ultrasonic every time the camera Is turned on

 

2- like you would an M except the shutter is always open.

 

3- no

I can't remember where I read it, but I saw a recommendation NOT to do a manual clean other than rocket blower, because the dust cleaning system on the sensor does not hold it firmly, and could be damaged by direct contact for cleaning. Worth checking before risking damage.

Download from the online manual (pg.278/279)...

 

 

 

CLEANING THE SENSOR

The camera is equipped with an automatic sensor cleaning function.

Every time the camera is switched on, the sensor unit is subjected to ultrasonic vibrations which removes most of the dust or dirt particles adhering to the sensor cover glass.

If any particles remain in spite of this (depending on their size, they can be identified by dark spots or marks on the recordings) the camera can be sent to Leica Camera AG’s Customer Care department (address: see p. 296) for the sensor to be cleaned at

a cost, i.e. this cleaning is not included in the guarantee.

You can also perform the cleaning yourself, as the shutter is normally open, i.e. exposing the sensor.

Safety and care instructions

Notes:

• Generally: To protect the camera against ingress of dust etc. into its interior, it is important always to have a lens or a cap attached to the camera body.

  • For the same reason, change lenses quickly and in an environment that is as dust-free as possible.

  • As plastic parts can easily pick up a static charge and then attract more dust, lens caps should only be stored for short periods in pockets in clothing.

  • As far as possible, cleaning of the sensor should be performed in a dust-free environment to prevent further soiling.

  • An 8x or 10x magnifying glass is very useful for the inspection before and after cleaning.

  • Lightly adhering dust can be blown off the sensor cover glass using clean and, if necessary ionized gases such as air or Nitrogen. It makes sense to use a (rubber) bellows with no brush for this purpose. Special, low pressure cleaning sprays such as "Tetenal Antidust Professional" can also be used in line with their specified usage.

Important:

• Leica Camera AG accepts no liability for damage caused by the user when cleaning the sensor.

• Do not attempt to blow dust particles off the sensor cover glass using your mouth; even tiny droplets of saliva can cause marks that are difficult to remove.

• Compressed air cleaners with high gas pressure may not be used as they can also cause damage.

• Take care to avoid touching the sensor surface with any hard objects during inspection and cleaning.

Well

My sensor had a couple of spots on it (I think it might have been a splash). So I cleaned it using a sensor swab from visual dust (as I do with the M). I can tell you it was a lot less scary than cleaning a Sony A7ii sensor (which wobbles about).

All seems well now.

      Hallo, ich habe mir vor Jahr und Tag eine M9 neu gekauft. Habe aber die M9 nicht benutzt , da ich lieber analog gearbeitet habe. Dann kam das Thema "Sensor" auf und ich habe um meine M9 zu prüfen einige Zeit mit der M9 fotografiert. Alles im "Grünen Bereich" - keine Probleme. Auf Nachfrage hat man mir gesagt, wenn da bis jetzt nichts passiert ist, dann kommt da auch nichts mehr. Sie brauchen nichts zu unternehmen.
      Also die M9 wieder weggepackt. Gestern nun M9 genommen , Objektiv angesetzt , Winterfoto gemacht .. und nix ! In der Mitte hell und an beiden Rändern irgendwelche Farbe. Karte formatiert. Das gleiche Ergebnis. Firmware kontrolliert und neu aufgespielt. Wieder Mist. Leica angerufen und 2 Beispielfotos an den Service gesendet. Aber man hat mir wenig Hoffnung gemacht.
      Es gibt keinen neuen Sensor mehr und wenn der es nicht ist, dann ist es irgendein Board, welches es auch nicht mehr gibt.
      So ganz kann ich mit dieser Sachlage nicht zufrieden sein. Eine recht teuere Digitalkamera mit weniger als 1.000 Auslösungen , gibt nach kurzer Benutzung und danach nur im Schrank gelegen, einfach den Geist auf und es gibt keinen Ersatz. Äußerlich sieht die M9 aus wie neu aus dem Laden. Die Update - Angebote habe ich auf der Leica Seite gesehen. Aber das kann ich nur als schlechten Scherz bewerten. Nach den Erfahrungen soll ich eine weitere große Summe in eine DIGITAL - LEICA investieren ?
      Gibt es ähnliche Erfahrungen ?
      Ich habe auch Digitalkameras von Nikon D3 und neuer die D810 von denen sind solche Probleme nicht bekannt. Na ja, die kosten ja nicht soviel.
      Es tut mir in der Seele weh, wenn ich nur denke die M9 einfach zu entsorgen. Es muß doch eine Möglichkeit geben.

      With mirrorless cameras exposing the sensor whenever a lens is changed, dust and other particles can become attached to the sensor.  as the sensors tend to heat up with use, I wonder if particles can become 'baked on'.  The question I have is, how frequently do people clean their camera's sensor?  And how do you clean your sensor, do you just uses a blower, a brush, wet clean with swab or a sticky gel like Eyelead?
       
      I believe that my ageing 'rocket' blower, where the bulb is made of rubber, is decaying and actually deposited fine particles on the sensor when I used it.  How can I check, and what is the design life of a rubber blower brush?  Some spots on my SL2 sensor took quite some removing with an alcohol-based wet cleaning kit and gel-based Eyelead.

      I love Tuscany in every season, but especially so in the fall or spring, when mist can transform the landscape & the mood of your photos completely.
