Canon Updates the EOS 1D Mark IV

April 6th, 2012


The EOS 1D Mark IV hasn’t seen many
updates in its time, and is just now being shifted up to firmware
version 1.1.1. The update is purely preventative in nature and
simply improves accuracy with soon to be released Canon 24mm and 28mm

To download the software, visit the EOS
1D Mark IV
, select your operating system and then select the
firmware update. Canon says that without the update, photographers
using the new EF 24mm f/2.8 IS USM and EF 28mm f/2.8 IS USM may be
left with overexposed photos.
