M9 Sensor Problems After Replacement

[Calzone]

How do u think Leica cameras
are shipped to the US for sale? Pretty sure they are not using submarines.

Huss,

I would perhaps say cargo ships.

Leica does not like to rush things. LOL.

I know first hand by being on waiting lists.

Raid, do not fly over the pole...

Hello Robert. It is not under my control now which flight chooses to fly over the pole or not.

Maybe I should only take along cheap digital cameras on plane rides?

 

[Huss]

Just use a film Leica as The Flying Spaghetti Monster intended. Who uses digital cameras
anymore anyway? That’s what ur phone is for.

It seems to be a very low probability event to get your sensor messed up by cosmic rays. The pixel errors can be corrected without having the sensor replaced.

Yes, using film cameras is always an option.

The vertical line is a stuck pixel which, on CCD sensors, affects the whole column in which it is located. M8 and M9 are vulnerable to this, and it is said that cosmic ray strikes can trigger the issue, so long flights at high altitude... It's unclear how Leica resolves this. I've had this fixed a few times, not been charged yet.


Suggestion: Contact Leica Service Dept by phone or email and see what they have to say...

Thank you for this information, Doug.

Don't take your M9 to the International Space Station.

I suspect a straight line of dead pixels is something else entirely.

Raid,

Pretty low risk of a "Cosmic Event."

Leica does warn in the owner's manuals of the digital cameras I own of possible Cosmic Ray damage when flying.

I should of stressed in my posts how low the probability is for clarity. I only kinda inferred the low risk.

It is a small issue after all, Cal.
I might as well use my Leica cameras day after day and don't worry about such issues.

You're more likely to be struck by lightning but, OTOH, it gives the worriers something else to add to the list of dangers out there.

We never had these problems with film and the mercury batteries lasted years. ;-) But that was before brokeh was discovered...

🙂Bokeh is the true enemy, David!🙂

How come the digital cameras on satellites don’t have a very short life because of cosmic rays? Look at photographs from Hubble or the rover on Mars Curiosity. They must have software to correct damage from cosmic rays.

At any rate I’ve flown with my camera equipment from Minneapolis to Chicago then a 13 hour flight to Shanghai then the same on return. Same equipment to Europe, several times. Haven’t had any problems; however my DSLR cameras have CMOS sensors. And not Leica!

CMOS and CCD sensors are affected by cosmic rays, I have been told.

Damn cosmic rays! Now I need another "Leica accessory" -- the 3-inch thick lead-lined cosmic box.

For those concerned, cosmic rays are a fact of life. Even if you're in that underground bunker. Cosmic rays will find you there too. We are lucky that most of space is just that -- space. Rays pass right through our cameras (and us!) without even contacting. Whoa! And I think cosmic rays are of a sufficiently low density we don't have too much too worry about.

I do wonder about cameras in space though!!!

Film? What's the deal with cosmic rays and film? There might be an advantage to film here.....

Many years ago, I remember we did a school experiment with some 4x5 film: We put the film out in the school yard, facing up, in a light tight enclosure. We left it out for something like 24 hours and then brought it in to process. There would be a bunch of little spots on the film, even though it was in a light tight container -- those spots were from nuclear fallout from all the various atomic bomb tests in recent history. I think this will still work even today.

 

[raid]

OK. How resistant to nuclear fallout are Leica cameras?

 

[Huss]

no need to worry about radioactive fallout when we know the sensors corrode in humid conditions. these things are definitely over built! well at least the boxes they come in are.

 

[raid]

It seems to me that after replacing the sensor, my M9 has a better buffer for back to back photos. Whatever was done to the camera, it is working well now.

All around us is radiation. A banana has naturally occurring Potasium isotope that is radioactive. Brazil nuts are pretty radioactive, and the radiation is naturally occurring.

Don't tell people who live in New Hampshire that they have natural high backgrounds of Radon due to the granite formations. Residents in New Hampshire have a high incidence of lung Cancer higher than the national average likely due to high background radon gas.

I live in Madhattan and the naturally occurring back ground is about twice that of when I lived in Brooklyn. Sand is actually low background, and like New Hampshire Madhattan has mucho granite and higher levels of Radon gas.

At work we do "radiographs" by placing radioactive target on top of Polaroid film to check beam dynamics and distribution. I work in an accellerator lab.

Perhaps some of what was recorded was naturally occurring background.

Epidemiological spatial studies can identify cancer clusters that are significantly associated with such factors. It is not a solid proof but it should be the first step for additional studies.
Worrying about things that we cannot control is not useful.

Raid,

Fact is radiation is around us in trace amounts whether we like it or not. When I eat a banana the naturally occurring level of radioactive Potasium is so marginal it is not worth considering.
