you are lucky. I do that to ALL my pictures in post processing. Makes you really focus on your subject. Now you can save a step in photoshop.

That looks like major vignetting. I dont think I have ever seen that from a P&S camera. I'd say you definatly have a problem.

What focal length are you shooting at? Does the vignetting appear at the widest angle and at full zoom?

07/01/2006 11:27:22 PM · #10

Could it be something that get s progressively worse? Or could it be from glare on the oceon.
I saw this article and wonder if the defect was already there and just got worse.

Close to the botttom of this report is a grid showing some vignetting problems.

It only appears at the widest angle. Any take on this?

You having any troubles with focusing?

If you have knocked a lens element around, you might have some troubles...

no focusing issue, its dead on most of the time. The camera is about 2 months old. No dropping or any physical damage

Based on that review it appears that that is one of the drawbacks of the camera at the wide angle end. Not much you can do. The only time this won't show in the image is on night shots where the corners are dark anyway.

If you zoom in slightly does the effect go away?

If i zoom in slightly it does go away. OH well i guess its a CCD problem. Can only be remedied by sending it back. Thanks.

You may have gotten some moisture inside your lens that is forming condensation. If that's the problem it should disappear if you keep the lens in a dry place for a day or two.

Actually no. What coolhar suggested may help but vignetting is the lens seeing the edge of the lens in the frame. This is a lens design problem. The edges protrude too far in front of the lens so they are visible in the frame at wide angle.

You said lense! so ur u saying u dont think its a CCD problem but maybe an alignment problem with the lense?And how do u explain this problem getting worse?

Hey guys! do you think my problems going to get worse? Because I may just live with it and focus out a bit. Very Difficult to ship a $240 camera back to the u.s. and the 90 days have expired so i'll have to pay labour charges. If it will get worse, i'll risk fixing it.
