Went out tonight and took some sunset photos with my D7000. I've taken over 800 photos with the new camera and all of a sudden I'm getting spots on my images. There were lots of mosquito's buzzing around, maybe it was that? Could it be dust on the sensor? I have it set to clean at startup and shutdown. The spots don't seem to be consistent. There is nothing on the lens that I can see. Any ideas? Here are a couple examples:
look like dust or oil spot.. i had the same issue two months ago. I brought my camera to a specialist and he cleaned the sensor. No more issue so far… I think that the D7000 is very sensitive to this kind of spot. Fabien.
I've had my D7000 almost two years and have been fortunate not to have dust collect on the sensor. I do use caution when changing out lenses and certainly don't change lens in the wrong environment. Hopefully, I've not just jinxed myself .

Thanks guys. Pictures were taken at f/10. I'm an 8 hour drive from the shop I bought the camera from and the Nikon dealer so looks like I better learn how to clean the sensor myself. We have a Source Store (Old Radio Shack) here in town and I noticed they have a cleaning kit on sale,
Any thoughts on this kit or recommendations for the D7000? It comes with the LensPen SensorKlear II. Is this a decent tool or is there something else I should be picking up? Keep in mind that due to my location, anything else I buy has to come through the mail.
I have used this and it did a great job. First, you should use a rocket blower to see if the dust will come off before resorting to a wet clean. You need to be very careful if you decide to wet clean the sensor.

looked at your pics, they looked like mine. definitely oil spots, not dust. had it too on my D7000. forums have mentioned this propensity for some D7000 units to spit out some oil from the moving parts inside. mine apparently did. careful when cleaning it; i wet cleaned mine (yeah, did it myself) and the oil spots scattered all over the glass that's protecting the sensor. did a few passes of wet and dry swabs and blown air as a last step until i got a satisfactory result. not completely cleaned (my first time) but clean enough not to ruin my shots. good luck with yours.
I don't know. Your mosquito theory may be right. Those spots are completely inconsistent between the two shots. Dust or oil will show up in the same spots on multiple images. Looks like they were shot only 5 seconds apart.
Check to see if anything is still there before you bother to swab your sensor. Set your camera at f22 and take a picture of an out-of-focus white wall and see what, if anything, shows up.
I blew out the sensor area and then took a few photos at f/22 of my wall and a sheet of white paper, both in focus and out of focus. Doesn't seem to be anything there now. So it must have just been dust or those darn mosquito's. I thought the spots would be identical on each photo if it was something on the sensor. If it was light dust and not stuck to the sensor, I guess they could move around with each shutter release.
I did a bit of reading on the net and dust seems to be something you just have to deal with, especially where I live. Now that I know and have done the blower cleaning, it's not that big of a deal and something I should probably do on a regular bases.

I think you're right.

That's generally correct.
So, if you're doing tests at f/22, and not seeing anything, you're good to go, and I probably wouldn't do anything. At f/8 and wider, dust is very hard to pick up at all, in part because the protective filter over the sensor is far enough off the plane of focus that the dust isn't rendered.
I would again mention the Giotto's Rocket blaster, as sooner or later you could get some noticeable dust. Thus far, in changing lenses, you must be doing a good job, so keep doing it!
I think you're probably seeing the mosquitos here...
1. If your sensor is now clean after only using a blower on it once it probably wasn't very dusty to begin with. 2. The spots are in different places on the images shot just a few seconds apart. This doesn't happen with a dirty sensor. 3. The shot was taken at f/10 & 55mm. There's no way to tell from the posted image where the lens was focused, but judging by the level of sharpness after reducing the image size it could well have been focused close enough to bring the mosquitos within the DOF.
If you are going to clean the sensor yourself go to the eclipse website and make sure you get the correct fluid for your camera. There are different types of fluids and using the wrong type can cause damage.

Actually that used to be the case, but no longer is. Photographic Solutions put out a statement some time ago (although they no longer seem to have maintained it on their site) that announced that after rigorous testing and use, they determined that the regular Eclipse fluid had no ill affect on the ITO coating on the hot filter and that the E2 fluid was no longer necessary and would cease the manufacture of it.
I use the Photographic solutions materials to wet clean my sensor, and they work very well. My only nit-pick (and I guess it is a petty nit-pick) is that the Type 2 sensor swab does double duty. As such it is sized for a 1.6 crop sensor making it not fully cover the height of the Nikon's 1.5 crop sensor design with using only one swipe.
I have similar issue before. If it is still under warranty, you might want to send it back to Nikon. That is what I did. The oily spots issue happens more frequently in the early batches of product. It seems you bought it not long ago. I am surprised to see it still happens. Of course, you might also want to avoid changing lens in dusty environment. Sorry, I am not familiar with DIY sensor cleaning.

Hi Pete, So, how do you clean the all surface of the sensor ? do you use it twice? Or does it need two swabs to be cleaned? I have just ordered the Kit eclipse + swabs ( size 2) and I just wondered about the way to do it.. Thanks in advance for your advices. Fabien.
>Hi Pete, >So, how do you clean the all surface of the sensor ? do you >use it twice?
I generally take a test shot and see where the debris is (remember that the top of the image is the bottom of the sensor) and then swipe the wet side of the swab toward the dirty side, then on the return swipe hug the other side.

Also as to the comments about being careful with changing lenses, while that’s good advice it’s not the major source of dust. If the comments I’ve seen posted by those more knowledgeable then me are accurate, the major source of sensor dust is from lens pump. Consumer lenses are not sealed and when they extend and contract when zooming they suck in dust and pump it into the mirror box. The act of the mirror flipping up and down during exposure acts as a fan to push it into the sensor chamber. So as careful as you might be when changing lenses, if you’re using an unsealed zoom lens dust is just a fact of life with digital imaging. Pete
Thanks’ a lot for your explanations. I think that learning to clean the sensor can be a true investment! As you said, the D7000’s sensor seems to be a “dust magnet”… so cleaning it oneself, as a normal and regular service, can be a good solution.
I could be wrong, but those look like classic dust spots to me. Unlike my D5000, for some reason my D7000's sensor is a dust magnet. I personally subscribe to the lens/ pump theory, since I use mostly zoom lenses and the dust seems to accumulate regardless of how careful I am when changing lenses (which is VERY careful). (I mostly do nature and landscape photography, so I am out in dusty places a lot.) In any event, regardless of the cause of the dust, I have learned to clean my own sensor. I use the Photographic Solutions Sensor Swabs Type 2 with Eclipse solution. First, I blow off as much dust as I can using a Rocket Blaster. Then, I swab, following the instructions. It generally takes 1- 2 swabs to get the sensor spotlessly clean, but I have had occasions where the dust was more stubborn (or they may have been oil spots) and it took 3 or 4 swabs to get the sensor truly clean. I also invested in a Lenspen SensorKlear Loupe, which is a great help in cleaning the sensor. The loupe has internal lights that shine down on the sensor and, with the magnification, you can easily and clearly see the dust (the included button cell batteries are awful, however; I eventually bought one of the cheaper substitute types which last 10 times as long and cost about a third as much).
If you own a D7000 and have taken a substantial number of shots with it, especially if you change lenses or use less expensive (i.e., not well sealed) zoom lenses, I can almost guarantee you that you have dust on your sensor, even if you haven't noticed it yet.
