Looks like the honeymoon period with Canon's beastly 5D Mark III is officially over. Over the past few weeks some users have noticed that light leaking from its top-mounted LCD can affect exposure readouts, and now the company has confirmed that it's indeed an issue. Essentially, the camera's meter can experience a shift in the readout whenever the LCD's backlight turns on in a dark situation -- ensuring frustration when composing shots. There's no word on how wide-spread the problem currently is, but Canon notes that it's "examining the countermeasures" and plans to circle back once it has a solution. Interestingl
