Dead pixel on sensor?

Take it back to the retailer and see what they say. 1/18,000,000 pixels? good luck persuading anyone that's unreasonable! (FTR, I looked at both the posted pictures and failed to spot the problem.)
 
I appreciate I'm being pernickety, but at the end of the day when you spend a considerable amount of money on something you do want it to be up to scratch. Upon further inspection it doesn't look like a single pixel, but rather a mini 'scar' on the sensor, affecting perhaps 30-40 pixels?
 
It's in a different area, looks pretty substantial to me though. It could be something on the sensor rather than dead pixels though, based on size even cropped that's a lot more than one pixel.

I'd take some pictures of a white wall, f22 or something and iso100 etc... That should show it more clearly. You may be able to use the dust delete software on the camera to eliminate short term, I think the 600D has that, it's under 3rd from the left option on the 60D (manual mode).
 
Are those 100% crops, what edited has been done on them they look quite undifind as if the images have been cropped and then expanded/stretched as said above a single dead pixel in 18million really isn't that bad

Needs to be remapped. Not sure how Canon do it, think you have to send it in? If it were dead it would have been black, haven't seen a properly dead black pixel since my 1D mk2.

If you think this is bad you should see what happens to works phase one backs, long missing lines and all sorts!
 
Thanks for the responses guys. I've been a bit more scientific and opened the photos up on photoshop. It's a spot affecting about 20 pixels. Using the ruler you can see the mark at approximately 1274 across and 2400 down (I don't know what the measurement is, I think it's in hundreds of pixels). The colour and location are slightly variable though.

I have remapped the sensor and, hurrah, it seems to have solved the problem. HOWEVER, I have looked at some of my photos before re-mapping and can't find the purple spot, so it didn't affect all of them. So I don't know whether it's gone away for good, nor what caused it in the first place...
 
I think you need to stop pixel peeping and enjoy the camera.

That's two threads already today with doubts about it. Get out and use it in the real world!

Thanks, as I said I do appreciate I'm being fastidious, but equally it's (for me at least) a piece of very expensive kit and I want it to function correctly!

Of course, but if you look hard enough, you will always find something.

You developing the very start of GAS ( gear acquisition syndrome). You have had the camera a day and already you are finding flaws with it and wondering if you should change it for something else.
Whilst on that path, you start thinking, well, maybe I should spend a little more and get a more advanced body.. Before you know it, you've dropped £5k on a pro DSLR and haven't actually taken a photo yet.

We've all been there and it's a slippery slope!

Just use the camera for what it was intended for. It's not broken, its not going to explode! Just enjoy it and learn.
 
Got to say that I couldn't live with that and you shouldn't be expected to. No harm in getting it checked out. If very new just give it back!
