[D3 / L1] Problem with RAW file !?!

[cboudier]

Hello,

My L1 is brand new, so my experience is very limited with it, but I already suspect a problem

NB : This only happen at iso 1600 or 800.

It's like if the files was incorrectly written to the card !?!
I can open these files with Lightroom, Preview or GraphicConverter, but not with Capture One, nor Lightzone (in fact, I can with Lightzone, but the image is completley purple).

Even if I can open them, I can see that there is a problem (see B&W zebra on the right side)...
I tried several times : always the same

There is also a strong banding : is this normal ?

I don't have that problem with my Digilux 3 or the L1.

The Digilux 3 RAW files are a little different than the L1 files however.

I also discovered that the numbers of pixels are different for corrupted files

iso 100 to 400 : 3148 x 2350 (the "good" files)
iso 800 : 3184 x 2358 (the "corrupted" files)
iso 1600 : 3184 x 2366 (the "corrupted" files)

Once converted to DNG
3184 x 2358 becomes 3164 x 2358
3184 x 2366 becomes 3164 x 2366

I get that row of weird pixels now and then in low-light conditions, too. It happens rarely enough that it has never concerned me. Perhaps I should ask Leica about it while the camera is under warranty.

No banding issues, though.

[cboudier]

No problem opening these weird files ?
What do you use ?

[cboudier]

The problem comes from my memory card...

I tried another one and no problem !

Anyway, the fact that only iso 800 and 1600 images are concerned is quite odd
I called Sandisk, they will replace my card.

[MJLogan]

The images open just fine in Aperture, except for the odd row of pixels. I don't use a reader--I just plug the camera into the computer's USB port.

I'll have to do a test to see if it's a card problem for me as well--I have several, and don't keep track of what came off which card.

I have to say that I don't think it's a card that is creating the banding. Check out this iso 1600 from a raw file. I think it's the sensor. As mine is in Solms for the now frequent kit lens wobble, I sent the attached image to Leica, NJ and they are forwarding it to Solms to have them check my sensor while it's there.

We'll have to see.
