Re: [OM] IMG: How can you get a dirty sensor with a camera that does not have interchangeable lenses?

[Chuck Norcutt]

On the contrary, I would expect the camera to be sealed precisely 
because the sensor cannot be cleaned without at least partially 
disassembling the camera.
The spot looks exactly like many such spots I've seen on my Canon 5D. 
So I also assume it's dust on the sensor.  Proof that it's dust on the 
sensor would be to take successive photos of clear blue sky from wide 
open to fully closed down.  At the LX-100's maximum aperture of 
f/1.7-2.8 the dust bunny may be invisible or nearly so as a very light 
gray cloud.  As the aperture closes down its shape will be more distinct 
(as in the image below) and it will get much darker.
I consider it a manufacturing defect.  Either the inside wasn't 
perfectly dust free when it was made or dust/debris has been generated 
by friction of mechanical motion such as by the shutter mechanism.
In any case I would expect a warranty repair... even it it's beyond the 
normal warranty period.  Adverse publicity to the hundreds or thousands 
of avid photographers on multiple lists is probably not a good thing for 
Panasonic.
Finally, the do it yourself guide:
