I have a stuck pixel. I had it a couple months ago, did the sensor cleaning trick and went away. Now suddenly it is back with a vengeance. I have done about 10 passes of the sensor clean trick and now the pixel is just stuck. Shows bright pink in nearly every RAW shot at every ISO/SS. Jpeg conversions seem to make it either smaller or bigger, but white . Very annoying! I just cloned it out of a set of 45 pics. I don't want to have to do this the rest of the time I own the camera. The only time it does not show is if I get lucky and it hits something nearly pure white.

Anyway, I still have 5 months warranty left, should I send it in to Canon? Can they do anything? I know crap like this can happen with 10 million pixels but I wonder how much is normal to accept. This is clearly visible at even small output sizes.

Samples (100% crop and full image - stuck pixels in forearm):

If the camera clean trick is not working then I would for sure call Canon and see what they have to say. I too would find it annoying if I had to clone out a dot on every pic for the rest of eternity.


Not sure why, but call me JJ.
I used to hate math but then I realised decimals have a point.

Yeah, I will probably call them after the weekend. You read about stuck pixels on the interwebs and it sounds like it is just inevitable and we have no hope. I found a cool utility that can automatically fix the stuck/hot pixels from your CR2 files called Pixelfixer, so I guess that is my last resort.

I hope I can get it fixed because I was hoping to sell it in a few months and put it towards a 50D. I would not feel very comfortable selling a camera that did this.

Use Lightroom or Adobe RAW to convert your files. They automatically fix hot pixels!

Yeah, but Lightroom is $300 and a PITA to use (IMO).

I have PSE6, but it is too hard to process multiple files at once to JPEG with ACR.

Yeah, ACR sucks for batch processing.

Too bad you don't like Lightroom. I didn't like it either at first, but it grew on me. Really easy to use once you spend a few days really working with it.

Also upgrades are a lot cheaper than PS upgrades, so if you get a new camera that an older Lightroom doesn't support, you don't break the bank upgrading.

But hey, if your camera is under warranty sending it to Canon will be an even cheaper fix :)

...and you get a choice of saturations, contrasts and even B&W ones! :-)

OP - I have one on my old 20D but Lightroom seems to map it out ok (but you obviously don't like this) - It's not that visible in most shots anyway.
I'm not sure what Canon's policy is on this, they may only repair/replace on a certain number (not 1 I bet)

It's not that I don't terrible dislike the lightroom idea, it just costs $300. I'd much rather spend that on a new lens or body upgrade.

Just talked to Canon and they said they would fix it, but of course I have a trip in a week and want to take my camera. And then my wife is expecting in 5-6 weeks. Hopefully I can get it in and back between those.

Just wanted to give a recommendation for a great free program if anyone else has this issue out of warranty. Pixel Fixer is working great for automatically removing the stuck and hot pixels from my images, automatically in batch. It only works on RAW files, but that is OK. Works really fast and you can input a whole folder at a time.

I'm still going to send in mine to get fixed since I'm in warranty, but I'm using this program in the meantime.

I have a stuck green pixel on my new 5dmkII that I was able to self-fix using the sensor cleaning method. I was thinking of returning it since I'm still under the 30 day return policy, but there is no guarantee that the next will be any better. I think I'll hold on to it and see if it reappears and will definitely send it in for warranty service at month ~10. Yours seems pretty obvious and if the self-fix doesn't work, I would send it in.
