S (typ 007) sensor fault?

When i tried take that photo of my roof, camera on tripod aimed up, me in very uncomfortable position trying to see through viewfinder, i suddenly realized that i have live view! Just sit down and look the back screen and take the shoot. I felt like genius for a moment ;-)

Now thats funny...!

If they did that, they did it well... I took photo from my roof panel (lots of stripes) at 45° angle and looked it side by side with one where blue lines occurred. At 1:1 scale i didn't find anything suspicious.

 

Anyway, retailer told me to take the camera, use it as much as you want and come back later with camera or money.

 

That's good. The important thing is you have no problems with your brand new camera performance

I am afraid that what they call "sensor reset" is probably sensor remapping.

Sensor remapping just tells the camera raw processor to "hide" the dead pixels by means of nearest neighbor interpolation.

 

That could cause artifacts in your image, as described here:

This remapping, is it something which is automatically done before camera leaves the factory?

 

I did look pictures before it (assuming that was done) and those were a mess. Like pixels at sensor and at image weren't at same place. No actual sharpness and strange color spots where shouldn't be any.

 

I did understand this remapping is sort of altering thing, but to this camera it improved the image quality significantly.

Anything affecting the customer experience should be "solved" before the camera leaves the factory.

All sensors are mapped (or should be... ) to correct for manufacturing faults before the camera leaves the factory.

On consumer-grade sensors there is always a certain number of dead and hot pixels that must be hidden. The less faulty pixels are specified the more expensive the sensor is.

Before you ask: fitting the S with a fault-free sensor would explode its price.

Thanks!

 

So in real life every camera has dead or hot pixels which are mapped off at the factory? And in this case mapping wasn't done until afterwards?

 

And remapping is thing which is done if pixels keep dying in use (fixing the fault)?

Almost every camera has single dead or hot pixels. These are not a big deal, as they can be easily interpolated out.

 

But not many cameras have entire columns of dead pixels, which are much harder to interpolate in a way they are not visible, and may require more postprocessing than usually needed.

I find this issue unacceptable on a pro camera, and would certainly demand a replacement. YMMV.

This is coming to hard to choose. To keep this and accept it's sensor or return it for replacement which takes months to come.

 

I live in small country with small markets, my retailer won't get many of these, bummer or not.

 

I told to retailer that i want one right after photokina 2014 and he managed to have one from early shipping. If he wants another it will come after all pre-orders (important customers and retailers).

If it's working and your happy with the results, why not keep using it until it stops? It might not.....

I've seen this on two sensors now. They need to be remapped. Maybe a bug in the firmware that drops the remap info out of the camera?

Maybe bug or maybe mapping isn't done in first place. Unofficial explanation was that one batch was shipped without it.

Thanks to everyone for comments and information. I decided to keep the camera, i got 3 year warranty with special note for the sensor.
