Canon has released a firmware update for the EOS-1D Mark III.
EOS-1D Mark III
Firmware Version 1.3.2 for the Canon EOS-1D Mark III camera incorporates the following fixes:
1. Resolves the following phenomenon: when the camera is not attached to a lens, power consumption may be higher than usual,
causing premature battery drain.
2. Resolves a phenomenon in which “Err 70” may be displayed when the shutter is released without a lens attached.
Firmware Version 1.3.2 is for EOS-1D Mark III cameras with firmware Version 1.3.1 or earlier. If your camera’s firmware is already Version 1.3.2, it is not necessary to update the firmware.
