Canon EOS 5D Mark III Review: Digital Photography Review

Custom Functions

	The custom functions on the EOS 5D Mark III are split into four sub-pages - exposure, Display/Operation, Others and Clear. It's less long-winded than in previous EOS cameras as some functions have been moved elsewhere and the AF settings now got their own menu tab.

My Menu

The 'My Menu' feature on the EOS 5D Mark III allows you to produce a custom menu made up of any of the cameras menu options (including custom functions) which means that previously buried but useful options can now be brought to a top level menu.
