Ugh. So I noticed a red pixel in one of my M9 shots. And then I checked the rest in the set and it's in all of them. Then I checked the very first images I took with the M9 and it's in those too. Then I noticed a blue pixel. And then a green one. I have three stuck pixels in my M9. Lame.


Now I've had it for over a month and this is the first I've seen it. But going back. It is in all of them since day one. And it only shows up on dark spots. I'm not sure if it's worth the fuss of returning it. Especially since I use the camera on a near daily basis for work. And 3 in 18 million (that I've noticed) aren't bad odds. But it's still irksome.
 
use lightroom as your raw converter and it automatically takes out those dead pixels. Pretty much all digital cameras get them - nothing you can do.
 
please ^ 🙄. not all digital camera experience it. there's always something you can do. return it and get it fix because a 7k camera should not have it!
 
My M8 has a couple ... and has since I got it! Like gavin says it's no big deal IMO.

YMMV of course! 😀
 
The title here says it all. As Gavin and Keith point out, your software can easily be made to touch these up automatically on import or conversion if it doesn't do it already. I understand that when you spend top dollar on top kit you want it to be right- but if the camera otherwise gave me no room for complaint, it would take more than this for me to want to return it.

When you have 18 million pixels there will always (if not at first, then eventually) be a few that drop out. Seriously.

Because the vast majority of people with prosumer/professional digital cameras use either ACR (lightroom/photoshop), aperture, capture1 etc raw converters with their digital cameras, they don't experience this. The reason is because all those converters automatically remove dead pixels straight away.

I'm not a 100% sure if the m8 has pixel mapping, but most digital cameras do now, and there's further proof that it's almost impossible to get sensors without dead pixels. If you're a JPEG shooter and don't use a raw converter, use the pixel mapping software on the camera which interpolates the pixel with a matching one from the surrounding area.

There's another trick you can use as well - sometimes dead pixels are just 'stuck' pixels and you can 'unstick' them. Put a lens cap on and do a 30-60 second exposure in M mode on the smallest aperture (f16-f22) a few times - check results before and after. A lot of the time this clears up at least some of them.
 
And I just realized it's an m9, not an m8 we're talking about. There should almost definitely be a pixel mapping thing in the menu of the camera - run that a few times and see if it helps.

note: Pixel mapping will only work with jpeg files, not RAWs.
