Canon has released firmware updates for the EOS 1D Mark III, 1Ds Mark III and 1D Mark IV.
The 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 70” may be displayed when the shutter is released without a lens attached.
