"We submitted our sample images to Canon and they confirmed the issue, calling it "Glow Dots," and saying that it will likely affect all PowerShot G1 X units. Canon further says, "Due to the limited circumstances under which the PowerShot G1X 'Glow Dots' phenomenon can occur, Canon does not plan to change the camera's specifications or offer repair service for this issue.
The light leak appears when the light source is in the bottom of the frame with the camera is held horizontally, and can appear even if light is directed into the lens from beneath, without the light source itself appearing in the picture. It also occurs when light is coming straight into the lens from the center, at just the right angle, but no light leak occurs when the light source is to the left or the top of the image. It is not visible in live view or during movie recording.
The conditions where the light leak is most noticeable is:
- Lens set to ~50mm equivalents (most of the shots above were taken at 26.8mm actual focal length)
- ISO 1,600 and above (we have seen it as low as ISO 800)
- >1/400 second shutter speed
- Light entering the lens from the center and below"
