I believe we're heralding in a new age of photography, for the first time in history people will truly be able to experience the many shades of black that are present in the world of complete darkness.

I got a response from Canon Europe:
--- Quote ---"Further to your enquiry, I can confirm that what you are experiencing has been recognized by Canon as a known issue and we would like to draw your attention to the following information. We very recently (in April) became aware of this phenomenon in the EOS 5D Mark III model which means that the AE sensor in the camera detects the light from the LCD panel when it is turned on and the exposure value is altered. The change is not significant as it is only altered by approximately 1/3rd of a stop but this can be noticeable. You can continue to use your 5D Mark III and the LCD screen can be turned off to receive the correct exposure.
Canon is now examining the countermeasures and once the countermeasures are finalized we will post the information on our website. Until then please accept our apologies for the inconvenience caused."

It seems that this issue is only an issue at 0 or -1EV, which falls outside of the designed 2-20EV range of the meter. At these light levels, you should not be using the in-built meter anyway, so Canon does not have to act on something that does not fall within of the design specifications of this product.
I hope Canon reads this, as I'd rather not have to send my camera away and not be able to shoot with it based on something that will not affect anyone under normal circumstances and is within the design limits of the device, but would feel obligated to repair for possible impact on future resale sale should they recall.

Brilliant. Canon should ignore an issue that they have determined is real.
Well that ought to drive product improvement.
It is attention to detail that makes a product, or an artist, great.
A known issue that might cause an error of 1/3 stop exposure is significant.
Fix it ... it's that simple.

I'm sorry, but I disagree. The equipment an artist uses has little to do with their greatness. You can have the best, faultless equipment available and still have little to no creativity or skill.
In terms of practice and the way an artist uses their equipment, we as photographers should use our camera meters within their optimum range - outside of that and we are jeopardising and risking our artworks. The amount of light where this issue is present is well out of that range. In these cases, the meter should not be used. It isn't a fault if it is something that affects a characteristic of the camera that is not a part of how it was designed to be used.
It is not like there are water leaks in the LCD or something (though this itself may need testing).
This isn't an issue and Canon have no obligation to fix it. We should instead be out shooting, not debating things that have no effect on it.

Maybe a firmware update that turns off the LCD backlight when the shutter button is half pressed and before metering starts could solve this issue for most people? No?
