Does Nikon D7100 have dust spots?

One of the few issues with the Nikon D600 is that it has a tendency to get dust spots.  See the related posts here (under 'Dust spots').  Some people are therefore wary that the Nikon D7100 might have the same issue.

In this post, I compare what my sensor looks like when I first got it and what it looks like now, after about 1000 shots.



When I got the D7100, the very first frame I took was a shot of the sky, in order to establish a baseline for the presence of spots (if any).

With contrast maximized it looks like this:

I now have about 1000 shots on the D7100.  Note: I change lenses frequently, at least once every time I use it.  I haven't noticed any spots on my shots.  On the other hand, I usually shoot at wider apertures.  For testing purposes I took a shot at f/16, which is likely as high as I would ever go for normal shooting (normally I shoot at f/8 or wider).

Here is how it looks at f/16:

With contrast maximized the f/16 shot looks like this:
D7100-1003-201303230930.jpg

For testing purposes I took a shot at f/45:
D7100-1004-201303230932.jpg

Here is the f/45 shot with contrast maximized:
D7100-1004-201303230932-2.jpg

For reference here is what my Fuji S5 sensor looks like (also at f/45):

I tried to remove the dust using the sensor cleaning function and by using a blower but they did not go away.  Anyway, I'm not in a rush to remove them since I don't see them in my shots.  However, I plan to bring it to the shop for cleaning after around 2000 shots.

    1. Hi Xiaoli. My D600 had many more dust spots after 2000 shots, and they were showing up at f/8. So, for now I don't think it is the same issue as the D600. I'll have a better idea after around 2000 shots.

  2. Hello,
    A big thank you for all your tests. Looking on the Internet are your most complete and tests the best. Have you tested the video function?
    Have a good week-end,

    1. Thanks Michel!
      No I have not yet tested the video function, partly because video is not my expertise. However I will test the video and post the results.

    1. Hi Sorin. Thanks for sharing your shot. It adds to the data to help people figure out if there is an issue or not. I am supposing from your file name that you have about 1500 shots. Is that right? Thanks.

      Bummer about the 2 stuck pixels. Perhaps it might be covered by the warranty?

  4. Hi,
    I d'ont know exactly how much pictures I was taken because the opanda could not read the shutter release from D7100..do you know another method that work?
    Anyway that 1500 it is I presume a good estimation...but a big lump of that was shoted indoor...testing lens and fine tuning.

  5. The dust problem on d7100 is aggravating...users from Romania start returning bodies for that problem and loosing money in the process.
    Also has appeared reports for the left most focus point not focusing properly.

    1. Hi Sorin. I have not yet seen evidence that the D7100 has a dust problem. If you notice my shot, there is dust but it is distributed everywhere unlike the D600 where it is mostly in the upper left corner.

      About the left AF point, I will test my camera. There is a useful test here: http://blog.mingthein.com/2012/07/03/how-to-tell-if-your-d800-d800e-d4-has-the-left-focusing-problem/

  6. Hi,

    I hope that the dust issue will vanish, but the fact is that yesterday I purchased a kit of spatulas wet and dry and cleaned the sensor getting rid of 90% of the dust. And that after not even 2 weeks and 1500 pictures from purchase. It is the first time in 3 years when I see that dust in my dslr's. Comparing at work with an friend canon 450D 5 years or so old and the amount of dust looked almost the same.

    But how I say...really hope to be just a false alarm :) Maybe was just my fault on getting so much dust...like in your pictures....:)

    1. Hi Sorin. Thank you very much. That is helpful to know. Perhaps there is some sort of dust issue as well. I will try to do a test for this. Thanks!

  10. Within a day of starting to shoot with my new 7100 I had a big ugly dust spot. I took the camera into Nikon and had a (free) sensor clean.

    Now, four weeks later, another dust spot has appeared - and I can't remember changing lenses more than once or twice in that time. With my old 5100 I used to change lenses frequently and in 18 months never had visible dust spots.

    So, in view of others beginning to report the same thing, I'm beginning to think that yes, perhaps the 7100 DOES have a dust problem.

    1. Hi RobM. The D600, which has a dust problem, had lots of tiny spots, so I think if the problem manifests in the D7100, it would also have many tiny spots as opposed to a few big spots. It is possible that the few big spots could have come from zooming, or from the lens itself (before it was mounted). In any case, hopefully your spots can be removed by a blower.

  11. I don't know, but I think the D7100 may have a similar issue to that presented by the D600. Sure, it may be just isolated cases, but Nikon clearly had QA issues with the D800 and D600. So why wouldn't it happen again with the D7100?

    I was planning on buying one this october. But now, I don't know what to do. :(

  12. I don't know, but I think the same QA issues that occurred with the D800 , D600 and D4 (if I'm not mistaken) may be also happening to the D7100. Sure, it may be the case of isolated incidents, but now Nikon has this history of problems with almost the whole line of new DSLRs.

    I was planning on buying a D7100 this october, but now I don't know what to do. :(

Thanks for your comment. It will be published as soon as we get a chance to review it, sorry for that, but we get lots of spam with malicious links.
