Rob Galbraith & Canon EOS-1D Mark III: The Saga Continues

Photographer Rob Galbraith has posted his latest take on the Canon EOS-1D Mark III after Canon has fixed the camera’s sub-mirror mechanism and updated the firmware to version 1.1.3.

“Without question, the sub-mirror fix improves EOS-1D Mark III AI Servo autofocus: it eliminates the camera’s big drop in autofocus accuracy when the mirror box gets warm or hot,” Rob writes. “Our experience is that it helps stabilize the autofocus performance so that the EOS-1D Mark III delivers about the same number of in-focus frames whether it’s warm or cold.”

Firmware 1.1.3 also played an important part in improving the camera’s autofocus, he said.

“But in our view, there’s more work to be done. In bright conditions, the EOS-1D Mark III still doesn’t match the EOS-1D Mark II N; at times the two are close, and at other times the EOS-1D Mark III’s autofocus performance is below what we consider acceptable,” he concludes.
