Question about Sony Cyber-Shot DSC-F55 Digital Camera

What causes translucent white circles?

I have been using my DSC-F55 for 2 weeks now and am having problems with my lens (I think). On most pictures I get translucent white circles when I take photos using my flash. They vary in size and could be up to 1 inch in diameter. I have cleaned my lens several times and cannot see any spots on the lens (with my naked eye). They also seem random in position. Does anyone know what causes them. Is it just a faulty lens? Could the spots be very tiny or on the inside of the lens? My camera is brand new. Regards Vijian

Re: What causes translucent white circles?

Vijian - I own several digital cameras, including the DSC-55. I have not experienced this problem with my camera. Try two things......adjust to "low" regarding your camera's flash setting, and secondly, put a piece os scotch tape over the flash and see if this helps. Be careful not to cover your light sensor on the front of the camera's housing.

Re: What causes translucent white circles?

Those particles are seen in several other cameras as well. There was a long thread on the Nikon forum and the most plausible explanation was that those circles are dust particles that are in the air very close to the lens; when the flash is used the particles are illuminated but because they are so close they are out of focus and show up as white circles. If the problem is defects in the lens that is easy to check for. They should appear in every shot and their position should not change. Dust, on the other hand, moves and it is dependent on the flash to make them visible.

There is a circle within the lens and when I take pictrues, there is a white shadow circle in the pictures. How do I prevent this from happening?


If the pictures taken are slightly misty, using a soft lens tissue (or spectacle cleaning cloth) wipe the lens delicately in one direction until the 'circle' has gone. Don't 'huff' on the lens as this will cause condensation INSIDE the lens.
If this fails to fix the problem, it may well be condensation build up inside the lens. If you have a sachet of silicone crystals (like the wee bags that come with a new pair of shoes), place the camera inside an airtight container with the sachet. Leave for minimum of 12hrs. This should absorbs any if not ALL of the condensation inside the camera.

I have dropped camera once, since after while clicking pictures at night in absolute dark, several round white small circles or spots are appearing on the image.But in full light area and in daylight...


Are these flash pictures? Are the spots in different places on each picture? If the answer to both questions is yes, the spots are dust particles in the air reflecting the flash back into the lens.

No setting can cause white spots on the picture, this is a fault.

By the way you can reset settings on this camera to initial state by simply removing and putting back camera batteries.
Alternatively you should have a reset command on camera settings menu.

My opinion is that this is a fault and not a settings problem.

Typically there are three kind of faults that can cause this problem:

1 - Dirty lens or water inside the lens:
The lens may be dirty inside, for example because of water condensation on internal surfaces, this will cause blurred dots or black dots. The lens must be taken apart and cleaned in this case.

2 - Defective CCD sensor.
The CCD sensor is the chip that detects the picture, if you get well defined white or colored spots on picture that is probably a defective CCD. I think this is the more likely in your case. To fix this the sensor must be replaced.

3 - Defective video chip on internal board.
This can cause any kind of problems, however it is quite unlikely.
It is an expensive repair.

Photosmart pictures have random white circles


It sounds like you have a photosensor that is going bad. If it happens 80% of the time, it is time to fix it or repair it. I have a friend who can fix cameras, he is cheaper and faster than the manufacturer.

DSC-T7 Blurriness


Try this test: Mount the camera on a tripod or set it on a secure base and use the self timer to trip the shutter. Doing this will totally eliminate any possibility of camera shake causing blurriness. If the picture is still blurred then there might be a problem with the AF but if it isn't blurred then the problem is either camera shake OR subject movement (or both).

White circles appear on the image. Why is That?


When shooting with flash in a location where there are many suspended particles, such as in a dusty area or on a snowy day, the image may contain white circles as shown in the picture below. Why does this happen? If the flash fires when a suspended particle floats right in front of the lens, the reflection of the flash from the particle appears more intensely than that of the subject, as the particle is much closer to the lens than the subject. Therefore, the reflection of the flash turns out in the image and causes an effect such as that shown in the sample image above. The closer the lens and strobe are located, allowing suspended particles to be exposed to more light, the more frequently this effect can occur. How can I avoid this effect? Ideally, it is best to shoot in locations where there are very few suspended particles. If not, you can use following method to prevent this effect. a) Avoid using flash by lighting the area as much as possible. b) If your camera has a zoom function, shoot at a wide angle. c) If you can attach an external flash, use the external flash to distance the flash from the lens.
