In anticipation of our European trip, I purchased a Lumix LX7 instead of toting my Olympus EVolt 500. The size of the Lumix and various positive recommendations seemed to be a good choice.

On our trip I shot nearly 700 photos with about 5% of them having a black diagonal shadow on them. There were no lens obstructions, the lens was clean, etc. Have any of you experienced this type of problem? My warrantee has recently expired, and now I am "groping for straws".


I am including one of the "afflicted" photos. Any help is much appreciated. Thank You.

My first thought was the camera strap was hanging loose and getting in the way. But it has a sharp edge you can see near the top right of the shadow. I think one of the aperture blades is hanging up. I'm no camera repairman so I'm not certain that's the answer but it looks like the sharp edge of a metal blade to me.

Could it be your sleeve of a shirt or jacket that got in the way of your lens.

I would tend to go with the shirt sleeve, do you hold the camera from below or above when taking you shots.

Thank you. Your aperture idea makes sense.

It is not a jacket or shirt sleeve. A shadow appears on at least 30 photos.

Thanks for you reply.

No, it is not a sleeve, etc. There were no outer lens obstructions.
Thanks for commenting.

Were they all that way? Something got in the way, either a lens shade, or something on t he sensor, or the lens, front or back.
All cameras have a screen to look at what you have taken. I look at every picture I take for exposure or any other problems.

Did you have a hat on?

You can see an image through the black shadow so it can't be something solid like a lens hood (my original thought), strap, sleeve, or hat, etc. I'm also skeptical about it being an an aperture blade hanging up because I believe the material they are made of is also solid. I think a trip to the repair shop is definitely in order. Good luck.

Were you holding sunglasses in your right hand while taking those occluded shots?

I agree that it may be an aperture blade timing. It didn't fully open at the same speed as the other ones. You got part of the blade as it was opening. It may need some type of lubrication or a loosening by a camera repair shop.

If this were a lagging diaphragm blade, I would expect the profile of interference to appear as either a straight line or an outward curve.

Also, the shadow allows some light through so it is not opaque as a blade is and jambed in one position and if continuing to move but somewhat more slowly, the shadow should grow from fainter in the central portion to darkening towards the edge of the picture.

The shadow is made by some semi-transparent item. And a camera strap or finger would be opaque.
