75% of images taken by this camera are ruined by white blobs, white halos, white circles, white comets, or other white artifacts that cover portions of the image. They show up randomly, with little rhyme or reason. Appears to be some sort of camera design flaw that allows flash light to bounce around inside the lens system. The artifacts move around in location from photo to photo, and are not the sort of thing you can fix easily in a photo editing program, so it’s a deadly flaw, particularly when they pock-mark your subject’s face. When this problem was brought to notice of Mr David Dentry, General Manager, Technical Support , Nikon Inc, he wrote “Our engineers have studied the problem at length and it only happens when there is particulate in the air. Smoke, water vapor, dust, etc. I am not implying that your area is dusty because a single piece of dust in the air can cause this. Again, there is nothing else we can do. Sorry.” but as per my observations the spots are appearing in the very clear air conditioned environment also.
