NX3000 "Check/No lens" issue.

The unthinkable happened, out of the blue, my NX3000 says "Check your lens" when I have an NX lens attached, doesn't communicate with the lens, and it can't control focus/aperture or anything. Also, when I put an adapter (which I am not sure if I had tried before) it says "No Lens".

I tried to reset, and now it doesn't say the "Check your lens" message, but doesn't communicate with any of my NX lenses.

Does anyone have a clue, or similar experience with another NX camera?

Do I have to do a mod/hack to accept adapted lenses?

In electronics, one of the first "gotos" is to inspect the electrical contacts.  If necessary clean them.  Since this is happening with all your Samsung NX lenses it could be that the electrical contacts that need cleaning are on the camera.

Sometimes just attaching/removing the lens will help clean the contacts but it sounds like you've already done that.

Have you recently shot in a dirty environment?

Your adapter most probably is only for MF (manual focus) and wouldn't have any electrical contacts.  If you've used it before you might have had to set the camera to ignore the lens.  But I don't think this would interfere with the NX lenses.

You could also check that the NX lenses are seating properly.  The lens shouldn't be loose or wobbly.  Also the lens should "click" into place.  This is a mechanical latch which makes sure that the lens contacts are properly aligned.  If the electrical contacts aren't aligned they won't work.  To remove the lens you should need to depress the "lens release" button

These are all just general tips.  Let us know how it turns out for you
