[Updated] Potential Recall of Canon 5D Mark III ; LCD Light-Leak

[L]ast week, reports began appearing around the internet that the new Canon 5D Mark III suffered from an LCD light-leak. According to initial reports, when the top-side LCD panel was illuminated, it would cause the exposure reading to drop by about 1/3 of a stop, potentially leading to under-exposure. Further reports concluded that bright daylight or overhead lights might also cause the same problem.

Addressing these concerns, Canon USA posted an advisory today recognizing that “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.” There is currently no recommended course of action, but Canon claims to be making preparations and will post a notification on their website when they’re ready. Their advisory can be read in full at the Canon USA website.

UPDATE:

Canon has identified the serial numbers of potentially affected 5D Mark IIIs and is offering free service for those who feel that it may be an issue for their shooting style.  Now that the problem has been identified and addressed, we can expect the Mark III to start shipping again.
