Canon has release the following EOS camera firmware updates:
1D Mark III Firmware Version 1.3.2
1Ds Mark III Firmware Version 1.2.3
1D Mark IV Firmware Version 1.1.4
These firmware updates incorporate the following fixes:
- Resolves the following phenomenon: when the camera is not attached to a lens, power consumption may be higher than usual, causing premature battery drain.
- Resolves a phenomenon in which “Err 02” may be displayed when the shutter is released without a lens attached.
I find it impressive that Canon continues to release updates for these older cameras.
