D7200, Oil spots? or dust? what to do?

Hi there!
I am having busy days at work and could not check my new D7200 thoroughly. I just took these photos today. Are they oil spot or dust? I'm an amateur and know nothing about the solve. I bought it from an authorized distributor of Nikon of my country and have 10month warranty left. Please help to diagnose and tell me the possible solve.

Probably just sensor dust. Lock the mirror up and shoot air from a rocket blaster bulb or similar device and you will probably get rid of most of the spots. Photographers have always had to battle dust, and I imagine always will.

BTW, do NOT use air from an aerosol can these have moisture droplets that can get on the sensor.

It's more of a problem with digital, than it was with film.

If a bit of dust lands on a frame of film before it's exposed, it will affect that one shot. For the next shot, you have a fresh frame of film.

With digital, when a piece of dust lands on your sensor, it tends to stay there, and affect every shot until it is removed. And they tend to accumulate.

I have to disagree. Dust on the film when exposed was almost never a problem for me. Dust on the negatives, though, was always an endless headache. It's way easier to clean up dust spots in post on a computer than it ever was in the darkroom. Just my viewpoint

Have you set your camera to auto sensor clean,i have mine set to clean at start up and switch off,its not perfect but it does help.

I suppose each of us is right, in a different way.

The problem of dust accumulating on a digital camera sensor, I think, is clearly much greater than that of it accumulating on film in a film camera, simply because with a film camera, you get a fresh “sensor” with every shot.

Dust accumulating on a negative after it's been exposed and processed is a different issue, not really related to that of dust present n a sensor or a frame of film at the time the picture is taken; and one that obviously wouldn't apply to digital photography at all.

Gently blow the dust and follow the advice about not using canned air It this does not work the you might want to try this,

Amazon.com : Sensor Gel Stick : Camera & Photo

Several people here have suggested it and I now use it and have had wonderful results. It is a little scary the first time you do it but is actually very easy, As with anything involving your camera, be careful and follow the instructions.

Looks like dust bunnies to me....you can fix with software

Giotto Rocket blower should do the trick.

Changing lenses brings in the dust unfortunately.

Yep definitely looks like dust. Don't sweat it. From personal experience I have had many meltdowns over dust on the sensor, zooming in 100% on images to search for it and thinking there was something wrong with my camera.

Now on it just comes with the territory. Try a rocket blower or cleaning yourself as suggestive above, or bring it to a shop to get it cleaned.

In in most instances the spots can easily be removed in PP and I only give the sensor a clean(be it done by myself or into a shop) when I have a major build up.

thanks guys. I've tried the auto sensor cleaning, didn't work. Probably I'll try the rocket blower

Before you go shooting that rocket blower into your camera body, check out this video. The first part shows how to correctly use a rocket blower. And if you still need a wet cleaning, it goes into that, too. @BackdoorHippie posted this for me back when I was having the dreaded D600 oil spot problem.

Just last week I wet-cleaned the sensor on my D610 for the second time--it had roughly 4500 shutter actuations on it. There were multiple sensor spots that wouldn't come off with the rocket blower. Once you do a wet-cleaning for the first time, you realize it really isn't that bad to perform. The video helped immensely.

Normal for digital nikon dslr bodies, I have never owned a Nikon body that did not at some point get some dust.

I'd think it'd be normal for any digital camera, with interchangeable lenses. Unless you only ever change lenses in a cleanroom, dust will get into the camera, and some of it will settle on the sensor.
