Canon 1D Mark III

We regret to inform that some units of the EOS-1D Mark III digital SLR camera (launched in May 2007) have been found to have an issue with the Auto Focus Mirror. This issue is limited to a specific range of units, and results in unstable focusing and AF tracking performance when using AI servo continuous shooting, particularly in high temperatures.

Please check the serial number as indicated below to confirm whether this issue is relevant to your camera. We are preparing to offer a free service from late November to customers with affected cameras who are experiencing the issues described.

We will announce additional details on our website as soon as they become available.

We offer our most sincere apologies to all who have been inconvenienced by this issue.

How to identify affected products:

If the serial number on the bottom of the camera is between 501001 and 546561, it could be affected by the “AF mirror adjustment issue”

Canon solved autofucus problem of EOS-1D Mark III

"We’re pretty confident this countermeasure will resolve the issue completely," said Chuck Westfall, a Canon spokesman and tech guru. "It feels nice to have a little bit of light at the end of the tunnel and know it’s not another oncoming train."

The AU$6,499 camera, geared chiefly for photojournalists who can appreciate features such as its 10.5-frame-per-second shooting ability, had won accolades for most of its design. But photographer and consultant Rob Galbraith dug up problems that cropped up in bright or warm conditions. The problems were also confirmed by others including Seattle Times photographer Rod Mar.

Canon was able to reproduce the problems. "What we found out after our thorough research is this issue seemed to manifest itself more in cases where the temperature was high," Westfall said.

Not all cameras are affected, but Canon doesn’t know which are or aren’t, so anyone having the problem should send the camera in to be repaired, Westfall said. Once it’s ready to begin repairs, Canon will publish instructions on how what photographers should do, probably in the next two or three weeks.

New cameras coming off the line don’t have the problem, he said.

The problem involves a mirror that directs light to the camera’s autofocus subsystem. "That mirror needs to be adjusted," Westfall said.

Single-lens reflex (SLR) cameras have a main mirror that directs light from the lens to the viewfinder, so photographers can see what they’re shooting. But some light passes through that mirror, traveling instead to sub-mirrors that direct light to the autofocus system’s sensor. When a photographer takes a picture, both the main mirror and the sub-mirror for the autofocus system flip out of the way to let light shine on the camera’s main image sensor.

The problem with the sub-mirror could mean the camera would focus in front of the subject or behind it, Westfall said. "If that sensor is not receiving reliable information, it’s not able to carry out correct focus prediction," he said.
