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

Thank you for using Canon products.

It has been confirmed that when the Canon EOS 5D Mark III Digital SLR Camera is used with the EF200mm f/2L IS USM and some units of the EF800mm f/5.6L IS USM lenses (the “Lenses”), the Lenses may emit an abnormal noise.

The Canon EOS 5D Mark III Digital SLR Camera does not need to be repaired as a result of this phenomenon.

The support measures for this phenomenon have been decided and they are as described below.

Phenomenon

If either of the Lenses is attached to the camera with the Image Stabilizer switch on the Lenses set to ON, the Image Stabilizer will synchronize with the autofocusing (AF) function and an abnormal noise may be emitted. This abnormal noise does not affect captured images.

This phenomenon only occurs when the Canon EOS 5D Mark III is used with either of the Lenses, and does not occur when such camera is used with other lenses.
