    I'm gonna meet a guy that's selling some used m43 equipment.
    Housing (EM-1) and lens is about 1 year old, with warranty.
    Is there a checklist you guys got when you buy used?
    The only things I'm certain I'll check is:
    Front and rear glass on the lens.
    The "frame" in the house (no scratches/damage). (Don't remember The English word).
    That they work combined.

    What more is important?

    I guess you mean the sensor.

    Also make sure the rear dial works properly, and doesn't skip any clicks.

    Make sure the rubber grip panels are not loose.

    Yes sensor!!! Thanks!

    "Rear dial", do you mean the "circular dial" on the back with the buttons surrounding it?

    To what's already been mentioned:
    -check the sensor by looking at reflections in light and shooting against a light background at f/22 - any dark blobs will be from junk on the sensor or filter stack
    -check condition of tripod thread
    -check for cracks/scratches on the LCD
    -check for green globs in the EVF due to possible sun damage (E-M1 special)
    -check for peeling leatherette on the body

    -don't worry about external lens element condition apart from permanent scratches, gunk and dust are easy enough to clean
    -lens internal element condition - hold up to light and look through it, tiny flecks of dust is okay but no mould or other UFOs
    -check the condition of the lens filter thread (usually plastic these days)

    -check lens and camera physical controls for grit ingress

    Hi, the dials on the top that control shutter speed and aperture... the rear one sometimes has problems where it misses some steps.

    One check I would try is with the lens mounted, switch to Aperture priority mode. Change the aperture to f/22. Assuming one of the front buttons is still set to the default of "Depth of Field" preview, you can look at the front of the lens (face the camera towards you) and hit this button and watch that the aperture closes down properly and opens up properly. You can rapidly push that button and the aperture should close then open back up quickly (should snap closed and snap back open).

    Also be sure to pull out the tilting back LCD screen and push it back in a few times to make sure it slides smoothly both directions.

    When you go to see the items bring a small flashlight and look through the lens for dust, fungus, haze.
    Bring battery for camera in case owner's is dead or missing.

    Love you all!
    The f22/depth of field trick showed some kind of dirt in the picture.
    The lens front was not washed, and there was dust on the sensor.
    No buy.

    Personally, if the price was right, I wouldn't let dust on the sensor bother me. I have cleaned my own sensors a number of times on several different cameras, always with good results.

    Maybe the E-M1 and its floating IBIS equipped sensor is scarier to clean yourself, I don't know.

    The price wasn't that right.
    And it is "scary" when a guy dont even bother try to clean up the front lens.
    It was not regular stains, but something sticky on it. A sticky matter on multiple spots on the front lens.
