To Users of the Canon EOS 5D Mark III Digital SLR Camera, and EF200mm f/2L IS USM and EF800mm f/5.6L IS USM Lenses
We have identified an issue that prevents users of the Canon EOS 5D Mark III from processing their RAW format images when using Digital Photo Professional Version 3.11.10. We would like to inform our users of our support on this issue.
Announcement regarding repairs to affected products displaying CCD image sensor phenomenon.
Following the repair of certain digital SLR cameras*1 at our service centers, we have discovered that when Eye-Fi cards*2 are used or when the general SD card is removed from the card slot promptly after opening the card slot, the camera will not operate normally.
It has been confirmed that, even when the lock screw for the lens hood on the Lenses is fastened, the lens hood may rotate when a certain amount of pressure is applied, but it will not detach from the lens. As a result, some specifications for the lens hood have been changed to address this phenomenon.
