This should be a 'sticky', but that's all up to the administrator of this forum ;-)

It seems that Canon has an undocumented feature built into the EOS 5D. Kinda like the easter eggs on DVD's...

If you have dead or hot pixels, instead of bringing it back to the store for replacement or having it sent to Canon to fix it, try the following:
Take a few test shots with the lens cap on (cover the viewfinder too) at different exposure length from 1 sec. and longer at several apertures and ISO's.
Enter the menu and select Sensor cleaning. Follow the on-screen instructions and shortly after the mirror has been locked up by the camera, switch off the camera.

It worked for me and for several others over at DPReview.com, where I was informed by users 'Guillaume paris2', 'MacGyver4321' about the possibility of remapping bad pixels myself using this methode.

Maybe the 5D has other hidden or undocumented features and it would be a great way to collect them in this thread.

If a pixel is really dead on your sensor or LCD screen then no software can reanimate that. Dead is dead!

Good luck.

I believe the 'remapping' occurs in the interpolation firmware.

Thanks for the hyperlink. I missed that one.

As it seems I haven't been the only one who has profited from the 'Sensor Cleaning trick'. I do have to note that my camera didn't have any dead pixels out of the box, just a few hot pixels (according to the DeadPixelTest program). So I can't actually say if the Sensor Cleaning trick also works for dead pixels. But I think it's worht a try if you do have some dead pixels on your sensor.
