After reading a post of someone explaining that some of the dust particles on the sensor of a Leica M9 melted into the sensor, I checked my M9 and found two sets of "dust particles" that apparently melted into the sensor. They do not go away by blowing or cleaning like they do on the Canon sensors. I read that the person with this problems got a new sensor from Leica. Anyone has this problem? Have you not checked your sensor for stubborn dust particles?
 
I blow mine clear occasionally and have it cleaned by an experienced repair technician twice per year. Nothing yet.

Of course your little poll automatically assumes that you have this type of dust so I will not be able to vote. :)
 
wonder if op tried cleaning with chemical and swab (or pay technician do it). when I had M8, some dust particles were too stubborn to leave sensor by using only blower.
 
The last time I cleaned my sensor myself I couldn't get it cleaned one mark just wouldn't move and I thought the sensor was damaged took it to my usual repair man half an hour later he had it spotless.
 
I do not know if the dust particles were melted onto the sensor, but early this year, I had spots that simply would not budge. My local technician thought that the dust was behind the cover glass. Leica replaced the sensor under warranty free of cost.

Probably sensor coating degradation. I had 'spots' that turned out to be anything but benign.
 
I cleaned my M9 sensor a few months ago, and my M8 sensor a few days ago. Now, both sensors are free of spots.
 
While it seems some M sensors are affected by coating degradation, I would have a professional camera technician clean the sensor before assuming the worst.

Leica must have a formal recommendation for what cleaning solutions are acceptable.

Sometimes dust accumulates solidifies on tiny oil droplet films or other contaminants and this sort of spotting can be stubborn to remove.

I have my DSLR sensors cleaned twice a year by an experienced technician and they come back spotless. I can not get them this clean myself. Many (most everyone!) people are more dexterous than me, so perhaps careful, skilled, patient owners could do a deep cleaning themselves.
 
If you have succeeded to clean a MM sensor yourself, you'll laugh about cleaning a M9 sensor. And whatever "someone" [explaining that some of the dust particles on the sensor of a Leica M9 melted into the sensor] claims, the description of "melted" into the sensor is clearly BS.

Whatever dirt he got into his camera by changing lenses in a shxtstorm should be removable by proper wet cleaning with the right tools.
And no, I have never had anything "melted" into the sensors of my M9 or MM and I clean both of them myself.
 
The dirt/dust can get between the sensor and IR filter.
Usually it gets there by blowing.
Try cleaning it.

Whether it's Leica, Nikon or Canon (or anything), I have spoken with a number of photos who feel they are seeing less "daily" dust but more (infrequent) dust that is really glued on sensor. Most feel that the larger the sensor and number of pixels the great the heat that is created, especially from intense rapid shooting sessions.

If auto cleaning doesn't keep the sensor really clean, the longer you wait to clean it, the harder to get it clean (not new news but more important if your sensor is heating the dirt on more permanently).

The M9 had the famous degradation sensor experience by many other M9s. I sent it to Leica and got a new sensor under the "Good Will" warranty. It happened to be majour design/manufacture error by Leica.

+1.

Cleaning is not a big deal.

As far as stubborn dust: I found that most dust comes off with just the use of a blower ball, and use of my Actic Butterfly or a wet cleaning has not been necessary. After owning my MM9 for 2 1/2 years I only have performed one wet cleaning and that was after my first 7-8 months of ownership. I generally check my sensor once a month and simply blow the few specks if any before they bond where a more extensive cleaning was required by having to draw off the dust electrostatically with my Arctic Butterfly.

I recommend as maintenance to check your sensor once a month to prevent any possible stickiness and more complicated cleaning. Also know that I use a Visible Dust magnifier with a ring of LED's so I can actually see any dust or oil vividly. Please don't make a big deal out of nothing, or confuse a now known design defect with routine maintenance that should be your responsibility.

Cal, you may have to bring this to the next meet-up.

John,

This Visible Dust magnifier with it's ring of LED's allows one to clearly see any dust or imperfection on a sensor. I can't see how anyone could do a cleaning or inspection without one.

I surely bring this magnifier to the next NYC Meet-Up.

It sounds like a great thing to have for the digital M Cal.

John,

I used this to check the Nikon D3X I bought that had less than 5K actuations: I found one spect of dust and used my blower ball to get rid of it. Seems to be the right tool for the job.
