To Users of the Canon EOS 5D Mark III Digital SLR Camera (Change of Displayed Exposure Value in LCD Panel)
Thank you for using Canon products.
Concerning the EOS 5D Mark III digital SLR camera, when the LCD panel illuminates in extremely dark environments, the displayed exposure value may change. Canon has decided on our service policy to address this phenomenon, so we would like to inform you of the details as described below.
Phenomenon
In extreme dark environments* when the LCD panel illuminates, the displayed exposure value may change. However, when shooting with a lens attached, this change in exposure value may not significantly affect the shooting results.
* Some examples of a dark environment are as follows:
1. When the body cap is attached
2. When the lens cap is attached
Affected Product
Canon EOS 5D Mark III Digital SLR camera
* Products whose sixth digit in the serial number is 1 or 2 are affected. For example, "xxxxx1xxxxxx" or "xxxxx2xxxxxx" ([x] represents either of the optional number.)
Support
When shooting with a lens attached, this phenomenon might not significantly affect the shooting results. However service will be provided to customers upon request from May 17 to address this issue. Please contact your nearest service center if you have any queries.
