Vertical line in Leica M8?

Since I sold one of the cameras I could care less about that one but I still have the replacement for original and if it happens again I expect Leica to replace the sensor for free.

 

Maybe they speak English differently in Atlanta from the rest of the world but, Ed, it's:

 

"Since I sold one of the cameras, I couldn't care less about that one...."

Thanks for the grammar lesson. Do you have anything else to add to this thread?

In this day and age, whoever expects electronic components to fail? When did you last have an Intel microprocessor fail?

 

While Leica take the stick for replacement costs, the iffy quality rests firmly at Kodak's door.

 

Never as far as I can remember. Never had a piece of memory fail either, that I can remember.

 

Well from the factory tour video the board on the back of the sensor is placed there I think by Jenopic??? (But I could wrong and that board on the sensor is placed there by Kodak) and then mated to another board, at least in the M9.

  • 9 months later...
Recently received my M8 back from NJ with a new sensor, $1250 later. It was 6 months out of warranty. What concerns me is if this problem comes back again in another year or two, this is going to get boring if I have to pay $1200 to replace a sensor every couple of years.

 

Mother of God! $1250 to replace a defective sensor?!?! :eek::eek::eek:

 

That's not service, that's robbery. I guess I might as well throw my M8 in the garbage.

That is correct, robbery. I had the sensors on both my M8 replaced for this line problem. I only have one of them now, sold the other, but I certainly won't be paying for a new sensor if it happens again.

If that is what it costs that is what it costs. These things werent ever touted as the most reliable on the block so its worth bearing in mind when buying second hand I reckon.

 

Trouble is after you pay in good faith, then wind up at about a year, and two grand, one Australian and two round the world trips for the kit and the repairs still are not done right and you have a new host of ancilliary problems you will likely give up and throw the whole shitty mess and associated lenses in the ceiling.

 

So spare a thought for us poor film users.

It is covered by warranty and should also be thereafter: an inherent manufacturing fault that makes the camera useless. Please do not let yourself to be convinced of the opposite too easily!
It is not a manufacturing fault, unfortunately it is well documented that all sensors are prone to this kind of thing. The cause is cosmic radiation taking out one or more pixels.Some pros, especially if they travel across the pole regularly,have their sensors remapped periodically. The thing about the M8/9 is that it becomes more noticable on an AA filter-less sensor. I wonder if the coming Solar Storms will have any negative influence.

Jaap,

 

Do you have any bibliography on this? I'm interested

Cosmic ray incidents typically don't result in permanent damage and when they do, they result in a hot pixel, not a column defect as seen here. This is due to a defect in the column that impedes the charge transfer process in the column so signal can not reach the output amplifier of the CCD. Here's an app note on cosmic ray and CCD: http://www.jai.com/SiteCollectionDocuments/Camera_Solutions_Application_Tech_Note/TechNote-TH-1087-CosmicRays.pdf

How so? A pixel line or dead pixel is a fault at the sensor level. What difference is an AA filter going to make?

 

Reminds me of the PDN reviewer who has idiotically claimed (more than once) that sensors without AA filters are more prone to noise.

There is a warning about sensor damage in both the M8 and M9 manuals. (M8 Page 125, M9 Page 165)

Meaning it's risky to take these cameras on an airplane??? I can't imagine spending that much money on a camera and not take it on vacations. In fact, the only reason I got an M8 was because I hated lugging a DSLR and voluminous lenses on airplane travel.
