    Use duck tape and your problem is solved :-)

    This thread is for the inevitable "My D7000 Sucks Im returning it and switching to Pentax" post or to report other D7000 "problems" you think you have.

    I second those sensor problems regarding hot pixels in video mode. Can others please check for those pixels in video mode (best seen on computer screen) in low light so that we can determine weather it's just a couple of us that are unlucky or is it across the board.
    Thanks.

    I've retitled this thread and deleted the comical post. I honestly made this thread to keep track of "real" D7000 problems.

    Can someone post a screen capture from a video or post a sample video so we can see the pixels? Bad pixels are pretty common in digital cameras.

    Here you can see two of the pixels, the other ones are not visible. They are best seen in motion as they stay still. I have about 6 or 7 of them.

    here's a screencap of mine. there's at least three visible here, although i can see about six altogether. blue in the lower center, red at top left, and green at upper right.

    Do the pixels appear from the start (ie do you get them if you have the camera off for an hour and in a cool location) or do they only appear after some time in video / live view mode?

    I would hope Nikon has a hidden firmware routine by which truly stuck pixels are mapped at the factory and discarded at a low level, but pixels which start over-reporting upon heating (hot pixels) are not as easy to deal with.

    Not that I have any solution - I'm just curious.

    i can turn the camera on cold after several hours of no use, put it immediately in live view with lens cap on and see them. someone on DPR suggested pixel mapping but i don't think it has that feature

    Hi guys,

    At what ISO was the video shot? Do you have a shutter for it, too?

    My best,

    Mike

    Interesting to see it appears Nikon isn't pixel-mapping.

    I assume from what you said then that you see the same stuck pixels in photo mode (at the same ISO and exposure length (and with noise-reduction turned off))?

    Hey I don't know too much about DSLRs yet but I'm lookin to get a D7000 but the report of light leaking and now the pixels worrys me, would you guys recommend waiting until Nikon figures it out? Or is it something that can be fixed easily. Also, I don't plan on getting an extended warranty from bestbuy (thats where i plan on buying it from) .. should i reconsider the warranty? I'm quite careful w/ my stuff so don't think its necessary but with the problems being reported, I'm reconsidering it. Thanks

    drab, strangely i don't see the hot pixels at high ISO pic shooting(see my original thread). it's only on live mode and video recording. i have the video iso set at 250, but i think it must do some auto ISO. haven't really figured out all the details yet. but if there was a way to fix it then i'd try it before exchanging.

    Not to ask a stupid question, but do you have High ISO noise reduction turned off?

    Same issue here, and when in photo mode all is good, no hot pixels.

    I have it turned off. But this should not affect the hot pixels, no?

    It is doing an AUTO ISO. You have to change the video mode to manual inside the menu.

    Historically no, it wouldn't get them, long-exposure noise reduction would. But this is a new camera with potentially new behavior and I'm just curious.

    Thanks for the information. There are lots of potential issues Nikon has had to address, and evidence like this points to how they are (or are not) addressing them.

    i also have NR off and have tried manual and auto video mode and get the same results. on my d60 that had lots of hot pixels at high ISO (800+) it never really helped to have NR. it just smoothed things, not really fixing the hot zones.

    Reporting one hot pixel (red) in the lower part of sensor, just left of center in my D7000. This would typically be considered "zone 3," and even on an expensive broadcast camera, this would not generally qualify for a warranty replacement of the optical block (I think you need to have three or more in zone 3). I'm probably not going to worry about it.

    How I found it: I tested my D7000 with the lens cap on at ISO250; NR = off; video = manual. I then scanned the LiveView image at 6.7x magnification by pressing the '+' button repeatedly. As long as your auto-focus area setting (regardless of whether you're currently using AF or MF mode) is set to either wide- or normal-area AF, you're able to scroll around the magnification window, using the cursor (Nikon D7000 user manual: p. 55). I'd be curious to know how many new D7000 owners there are out there who don't have any dead pixels.

    I suppose I should feel "lucky," if I only have one dead pixel, and that it's not in the center of the screen. At work we have three $70,000 Sony HDW-F900R HDCAM cameras. All exhibit several dead pixels each, if that makes anyone feel any better.

    Hi all,

    I'm not getting 'what' is wrong.

    If the sensor is recording a pixel incorrectly, that would be a very bad thing - I would be very disappointed.

    If the what it is trying to record is out of its range (ability or sensitivity), that's another thing entirely.

    Could one of you smart guys clear that up for me?

    My best,

    Mike

    it's definitely weird that this isn't happening during pic shooting, only video. anyway, got a pic with another cam of the messed up areas.

    It's not "out-of-range"--it's a defect in one of the pixels on the sensor. On high-resolution sensors, finding two or three dead pixels on a sensor is fairly common.

    even if this is within 'tolerance' (which i find it hard to tolerate for $1500), is there any way to fix this in post? it's obviously way easier to correct in pix, but for video?

    After a little experimenting I found something interesting. For those of you who have hot pixel problems: pit on your lens cap, turn on the live view and increase the iso to about 5000 with the shutter at 50. You should now clearly see your dead pixel. Now, while looking at your screen increase the shutter up to around 320 and watch the dead pixel "disappear". At least for me it does.

    I don't know. In pro video cameras, you're able to map out bad pixels via a "maintenance" sub-menu. That image you posted of another D7000's sensor is bad enough that I would return it. Since my dead pixel is in the lower part of the frame, I probably won't worry about it.
