Article Summary:

Canon has issued an advisory about its new 5D Mark III SLR: “In extremely dark environments, if the top LCD panel illuminates, the displayed exposure value may change as a result of the AE sensor’s detection of light from the LCD panel.” Users have reported that shining a light or torch onto the LCD panel affects the camera’s exposure settings too. Canon do not, as yet, have a fix for the problem and the company “is now examining the countermeasures”.

The advisory requests that people register their cameras with their regional Canon office, as this will allow them to be notified by email when a fix becomes available.
