    Oh well, the spots show up also with the other lenses, and looking back
    at all pictures I took, they seem to have been there from the very
    beginning.

    I guess it's time to learn how to clean the sensor?

    Do you have the dust removal feature in your D7100 turned on?

    OK! This is a skill every DSLR changeable lens digital camera should
    master for persistant dust which the camera system is unable to handle.
    I had my sensor wet cleaning baptism with my D70 which can be best
    described as a dust magnet.

    You mean using the "Image Dust Off Reference picture"? No, not yet at
    least.

    Thanks for the links. I can actually see one of the dust bits on the
    sensor with the naked eye. Would it be wrong to just try and blow it
    away with air?

    Also, I went through all photos I took since I got the camera (just
    before xmas) and the spots were already there like the day after I bough
    it, only I had never noticed them! I wonder if I can return the camera
    and ask them to have it cleaned for me?

    There is that if you are shooting RAW and you are using the Nikon NX
    software, but it is not always a foolproof way of dealing with dust.

    What I was referring to was the menu setting which enacts sensor dust
    removal by shaking/vibrating the sensor using one of three options
    found in the *Setup menu*.
    Open the menu and go to *Clean Image Sensor* and you can *Clean Now* or
    you can *Clean at startup/shutdown*.
    If you choose *Clean at startup/shutdown* you can select either of
    those two options, or both and turn it off.

    I have my D300S set to clean at startup, and I very rarely have to
    resort to wet cleaning.

    Blowing the dust off with a bulb type blower such as a Giottos Rocket
    should always be your first option.
    NEVER USE CANNED/AEROSOLs as they can contaminate the sensor with propellant.

    You can also use a clean sensor brush, charged with a few puffs from
    the Giottos blower. to make a single pass of the sensor and to brush
    out the mirror chamber. After each brush pass clean the brush bristles
    with a few puffs from the blower.

    They might clean it for you if you have a good relationship with the
    camera shop, but there is no guarantee that they are capable of doing a
    better job than you could with the right tools. Not every camera shop
    has the skills to do this sort of thing, and finding a service center
    to do it might cost some fee. I don't believe dust on a sensor is
    covered by warranty.

    So my recommendation is learn the skills yourself.
