    Someone familiar with the phenomenon that the NEX cameras very sensitive to dust on the sensor. However, it is not substance but it seems to me more on oil splashes. Pretty fast I have him only 1 month. Or the sat there already and here I of course him when not checked.

    Well, I've noticed that the NEX is a bit more prone to dust on the sensor than dslr cameras because of the short registration distance & large diameter lens mount.

    Oily residue I have not seen though.

    I don't have this problem with my NEX.

    What comes to mind however, is that if the camera body is statically charged then it will attract dust and other particles... and if the mount is open, then also onto the sensor itself. I am just speculating and could be wrong. But in very cold climates, the camera goes in and out of heated indoors and cold outdoors, and always getting in contact with wool or nylon clothing and also gloves. Could this statically charge the camera body, perhaps?

    Touch wood, haven't experienced any dust problems yet. I have so far thought that the NEX is one of the better cameras when it comes to dust spots. My Fuji X Pro 1 is also good. My Canon DSLR's are terrible though, I'm always cleaning the sensors on those!

    And no mirror! Dust is a fairly common problem for me, but it's an easy problem to deal with.

    As far as oil goes...I have no idea where that would come from. Only thing I can think of is the shutter was lubed too much or incorrectly in the factory (if they even lube shutters these days)?

    Haha! I guess I don't miss what I don't see when I look inside the camera. :p

    If my static hunch has some influence, I'm thinking plastic DSLR bodies may keep any accumulated static for longer because plastic is an insulator. A metal body (like the NEX) would discharge small amounts of built-up static, the moment we touch it.

    Perhaps...

    Both my DSLR bodies are metal, but I would say its a good theory nonetheless.

    Its very easy to clean dust of the NEX sensor, but for oil you might have to use specialized cleaning swabs. Better take the camera to service center and let them clean.
    If done wrongly the cleaning may have some unrecoverable effects on the thin AA filter over the sensor.

    Yes I am also planning. Everyone says it's easy, will also be true but I bring him to a specialized company.
