How to work around
    it?
    
    I bought this camera, a Nikon D500, secondhand from a store.
    Cameranu.nl in the Netherlands.  Not a good idea to buy
    there anymore. That may be clear if you look at the picture
    below.
    They give a year garantee on their stuff and everything is
    checked before it is sent to the buyer. No idea what they
    checked with this camera. Maybe that it WAS a camera?
    I bought this camera after my adventure with the D750 that kept
    to get very dirty even if you did not change the lenses. It
    seemed to come outof nowhere. And then now this one....
    supposedly to be completely in order.
    Later I bought a brandnew D780. And yes, after a few months the
    same problems started to arise. I (with my heart in my throat)
    cleaned the sensor with swaps and yes... I got rid of a lot of
    dust, but other particles had dicided to keep residence on the
    sensor. I was considering to buy a bridge camera that had does
    not have interchangeble lenses to get rid of the dustproblem.
    But then my brain had a bright moment.
    If we need to put the aperture to f22 to check for dirt because
    you do not see it otherwise..... would there not be the
    solution? Do NOT close to f22. I changed from shutterspeed
    choice (where the camera decides on the f-stop) to aperture
    choice, where I did not close the lens further than f11. In
    most cases with 1/8000 as a maximum that will do. Problem
    solved.
    Of course it will not mean you never have to clean the sensor
    again. But when you do and some particles stay behind it is not
    a problem.
    I use my camera now with much more pleasure than before!
    Here is a picture as an example. It is clear this camera cannot
    be used in this way. 

    KISS
