Exclamation HEEEEELP brand new Canon 7D by 3 months with HOT or DEAD pixels

[NaughtyDanny]

When i seen them in live view is when i zoomed in, and when it appears on the photos they appears at all ISO, 100 to HI. The last test i did it disappears at ISO 100 but appears to the next ISO 160-6400

OK. If you have to zoom all the way in when using live view to see it, and it's in the same place, it's a hot pixel.

As I said above, it could resolve itself, but there is nothing you can do about it. It might be there sometimes and it might not. The ISO won't make a difference. The only thing that can make a difference is exposure time - you're often more likely to see them in longer exposures as the sensor heats up more.

Sadly, this is a fact of the current sensor (and LCD) manufacturing methods. You have to live with it.

I need to say that the last photo, the black i attached here was on1/80 speed. so it wasnt a long exp.
One more thing, does this problem its common or just was bad luck for me?

OMG thanks anyway.

No, 1/80th isn't very long but, as I said above, it happens.

As for how common it is, it depends on who you ask. Generally, it's less common than it used to be but for several reasons. Firstly, manufacturing techniques are better. Secondly, it's less common on CMOS devices, and we tend to use many more CMOS than CCDs now. There's also the fact that, just about every camera that shoots in jpeg won't ever show it's stuck or hot pixels, they get mapped out so you don't see them. Finally, with more and more pixels on a sensor, dodgy ones are often harder to spot.

Your post prompted me to go looking and I've got one exactly the same as yours. Never noticed it before and I'm something of a pixel peeper!

What I would say is that you have been unlucky in noticing your hot pixel. You could have had your camera for a decade and never noticed it. Sorry!

Hahahahah, im a little bit obsesive with perfection and more when we are talking about a non cheap camera at all.

Thanks for all.
