Canon has confessed that their new high end EOS 5D Mark III DSLR suffers from a light leak. Here’s an excerpt from their advisory to US customers.
In extremely dark environments, if the LCD panel illuminates, the displayed exposure value may change as a result of the AE sensor’s detection of light from the LCD panel.Canon is now examining the countermeasures and once the countermeasures are decided, we will post the information on our Web site.
How does a company that has decades of experience making some of the world’s finest cameras let this slip through?
Apparently the 5D Mark III isn’t the only Canon camera with a light leakage problem. A couple of weeks ago Imaging Resource reported they’d found a light leak problem with Canon’s hot new G1X prosumer camera.
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.”
