I have used the KM 5D for about one month with results that far exceeded my expectations.
Since last week I've noticed a "smudge" like shadow in blue sky pics. I thought initially of the lens since the pics that had the "ghost" were taken with a specific lens.
Today I went through all my lenses including primes taking pics of the sky and all lenses had the "ghost". I'm attaching a sample pic; the "ghost" is at 1 o'clock close to the upper edge.

Any ideas will be greatly appreciated.

CCD sensor dust


read the manual re: sensor cleaning - do not attempt unless the instructions are clearly understood

mount camera upside down on tripod

wear a (cheap) dust mask (to avoid your wet breath from contaminating sensor)

initiate camera sensor cleaning mode (depowers sensor to eliminate static charge)

using a MANUAL bulb blowervigorously 'blow down' interior of chamber WITHOUT touching anything

cleaning involving actually touching the sensor is not for the faint of heart

good luck

This is a UFO - Unidentified Foreign Object (on your sensor)

Thank you for the suggestion.
I finally summoned up all my courage and cleaned the CCD. Result: the UFO on the sensor is gone but now I see a little spec in the viewfinder; it doesn't appear anywhere on the picture.

Is there a way to clean the viewfinder?

Thank you

To clean the mirror, just turn the power off, take the lens off, and blow on it the same way you did for the sensor. I would be even less inclined to touch the mirror than touching the sensor. It is a front surface mirror and can scratch very easily. Dust/smudge on the mirror is annoying, it does not dammage the picture. A scratch would be more annoying to me.
