Lately I've noticed that there's some vignetting on my pics (I used a FZ10). I didn't have this problem this summer or 10 months ago when I first bought the camera. Interestingly enough, the problem is exacerbated when I take vertical (proper term???) shots.

These 3 pictures were taken with a lens hood on (+uv filter)

EXIF Data:
Shutter Speed: 1/100sec
Aperture: 3.2
Focal Length: 21mm
Lightsource: Daylight

EXIF Data:
SS: 1/50sec
F-#: 2.8
Focal Length: 12mm
Lightsource: Unknown

F-#: 2.8
Focal length: 15mm
Light source: Unknown


This one was taken w/o lens hood

EXIF data:
Focal length: 14mm
Aperture: f/4
Shutter speed: 1/400sec

So what could be the root of this problem? :?:

that's nothing that a little bit of photshop won't take care of .......i think that would be normal using the lens hood at that focal lenth..somebody correct me if i'm wrong...

What about the picture w/o the lens hood? And I didn't encounter this problem half a year ago, it seems to have started this fall.

I can not speak for your FZ10 but mine always did that, as does my FZ20. The brighter the lighting the less noticeable it becomes. Not noticeable at all at normal viewing size.

Vignetting happens on my FZ10 as well, no matter I use the original lens hood + 72mm, phayee adaptor + 62mm filter or even without any lens hood. Though it is annoying, vignetting is just so common on many wide/long zoom lenses (on SLR system as well) and almost can't live without it.

I think it also has something to do with your aperture; the larger the opening, the more vignetting. I have no idea if the lenshood makes a difference; I always have it on, when outside

Interesting link about the aperture. I guess I'll pay attention to that the next time I'm taking pictures. Thanks everyone.
