Canon USA has released a product advisory to users of its EOS 5D Mark III, confirming possible light leaks when the camera is used in "extremely dark environments."
In these situations, "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," says Canon.
"Canon is now examining the countermeasures and once the countermeasures are decided, we will post the information on our website," it adds. At the moment, it remains unclear whether Canon will be able to resolve this issue via a firmware update or whether it will be forced to issue a product recall.
Canon's acknowledgement follows numerous reports that surfaced online from EOS 5D Mark III users. It comes as its other flagship camera, the EOS-1D X, which was unveiled in October 2011, faces another delay.
Last month, Originally, Canon's 1D X camera was to be released in early March, but following unidentified development delays, the firm was forced to admit last month that the camera would only be released at the end of April. Now, Canon says that the camera will only go on sale from mid-June 2012, just a few weeks before the 2012 London Olympic Games.
"We would like to apologise for any inconvenience caused to customers," says a Canon spokeswoman.
