Canon offers EOS 5D Mark III and EOS-1D X firmware updates

Canon has released firmware updates for its EOS 5D Mark III and EOS-1D X DSLRs. Both updates claim to improve the user's ability to control autofocus in Live View mode when wide angle lenses are used. Firmware 2.0.7 for the 1D-X also fixes a couple of issues, including a problem with vertical lines appearing when long exposures are used.
