I've just (as in 'bought today') upgraded to a Nikon D5100 (from a D50). It's nice and featureful (if a little shorter and smaller in the grip than I'm used to), but. It has a stuck pixel. Yes, I know, just one defective out of 16.2 million effective. So. Is it worth going back to the shop and seeing if they'll exchange it? or should I live with it?
And here I am still with a D50, all alone. *Sniff Come back and join the club with me! You've had it for a day, if the shop don't take it back there's something wrong.
how did you even notice? I can see it being irritating for astrophotograpy, but otherwise, how noticible is it?
^Just as annoying as a single stuck pixel on any monitor- as soon as you transfer & open the pictures in your photo editor of choice, it'll stick out like a very small but sore thumb. I suppose you could always edit out the bad pixel on every image, but a defect is a defect; if it was sold as used or B-grade stock, then that'd be a different matter...
Its quite noticeable from the rear screen - all I have to do is zoom in a little and it jumps out at me.
Bad QC from Nikon, and I'm really surprised about that. Chances are that the bright pixel would be altogether lost in a lossy format like JPEG, however as a matter of principle I think you should replace it.
Well, with the floods in Japan and Thailand, I believe they're producing parts in Hong Kong for now. Not sure. But that should say enough.
I must have bought the last one, as they've even sold the display model (so no insta-swap), and have no idea when they'll be getting more in stock. It didn't show up in a quick crop and print in store, but if it's actually visible in normal use, I'll see what can be done under warranty.
All camera sensors have stuck pixels (some times called hot pixels), but some can be more visible than others. The easiest way to see them is to take a picture with 30 seconds exposure and with the lense cap on. There should be a few of varying brightness and colour. To fix this Nikon will remap the pixels telling the camera sensor to ignore the stuck pixels. For Canon there is a trick which allows you to preform the pixel remapping yourself. http://photography-on-the.net/forum/showthread.php?t=918913 Unfortunately for Nikon cameras you have to send it back to a Nikon service centre. (I think this is free). This bit of software seems to be able to remove stuck pixels from RAW and Jpeg photos. http://www.pixelfixer.org/
Herewith, an actual attempt at a photo, rather than 'what does this setting do' snapshots. The pixel in question is (or would be) just to the right of the second hand's lume spot.
...which is the point. As Lenny says upthread, it just disappears in normal use, so while I don't like it being there, unless the sensor develops the measles, I'll put up with it.
