Canon 5D problem - a stripe on the picture

Its right in the middle of the picture.
5D sensor consist of 2 1dmk2 sensors bonded together so probably the bond has unhitched.

Let me ask Jon about this one. If this is the case, a trip to the service center would probably be best.

Yeah Jon is the man for corroboration

Er. . . No. I'm not sure where you got that idea, but you may be confusing the DiGiC processors with the sensor, and the 1D Mk II with the 1D Mk III family, which has dual DiGiC III chips. The pixel dimensions of the 5D and 1D II are also almost the same size. But the 5D has a single-chip sensor of 24x36 mm and about 13 MP; the 1D Mk II has a sensor of 19x28.7 mm and 8.2 MP, so neither in pixel count nor in area would bonding two 1D II sensors together give you the 5D's sensor. In addition, the design of the sensor means it has contacts around the edges, outside the active sensor area, on all four sides; placing two of these side-by-side would leave a gap in every picture taken.

To OP. Yes. it looks like a camera issue, since you're seeing it with two different cards and a variety of lenses. If it were in the card, I'd Are you able to associate it with any particular shooting modes? With common characteristics of the locations you're shooting in when it happens? Cell phone or other outside RF-type activity? It's the transient nature of this that makes it tough to track down. Judging by the colour, that was taken under some kind of gas-discharge lighting; if that's a common characteristic of the problem shots you may be seeing RFI from a "static flicker" in the light, one of the occasional "bzzzzt" sounds you'll sometimes hear from them if poorly shielded or if the current isn't as clean as it might be. That would be very hard to duplicate, and I don't think it'd be repairable, short of a tin-foil hat for your camera.

Ok may be not 2 sensors bonded but according to this whitepaper : http://www.usa.canon.c​om …0Papers/Canon_C​MOS_WP.pdf

So perhaps that strip is actually gap between 1st and 2nd process?

As of 8/16/2006, when that document was created, it was probably mostly correct. So it's 2 years out of date.

I'd trust Jon on this. He is the one I go to. But as for the problem itself, so terrible, and sorry you have to suffer for it. The replacement of the sensor will cost some, but better have the camera working 100% and you don't have to guess if it'll work right.

Hi Guys.
the stripe isn't in the middle of the picture.
I just came back from the camera shop, where i gave them the CF card.
They are about to send the RAW images directly to Japan to Canon labs.

Jon, to your quesion.
I am not associated or a fan of any of the modules (AV/TV/P/M) , i mostly use Manual, but both AV and TV are an option i use frequently.
the light terms differ between the deffected pictures, it can be daylight or night as well.

I must say the tecnician sounded and looked professional and was realy assuring me saying "if it was a sensor, no way i couldn't reproduce the problem".
yet, I am open to hear your opinion, and so is the tecnician.
so keep on the brain storming, you are really helpfull.

Thank you all for your efforts so far.

No. What they said is that it takes more than one (three, in fact) photolith exposures to mask a FF sensor. Sensors are exposed under precise machine control, and each is individually tested. An imperfection in a sensor chip would result in it being thrown out; it'd take a manufacturing failure to cause a gap between two photolith images, and that would recur on multiple wafers. It'd also be consistent, not intermittent.
