Ease of Operation
In order to provide ease of operation that befits a new-generation EOS-1D series camera,
Canon has thoroughly investigated ways to make camera operation easier. The camera
retains the EOS Digital line's basic operation method with the Main Dial, Quick Control
Dial, Multi-Controller, SET button, and other buttons to select and set various functions.
Also, the ISO speed button, AF Start (AF-ON) button, Picture Style button, and Memory
selection/Image size/White balance function button have been newly added to make
camera operation easier.
With the older EOS-1D series cameras, the basic shooting operation logic consisted of
holding down a button and turning the Main Dial or Quick Control Dial to select a setting.
However, with the EOS-1D Mark III, when you press a button, it remains active for a while
so you can let it go and then turn a dial to set something. Also, the three buttons on the
top left of the camera accept double pressing. You can therefore set something (except
AEB) with just one button.
With the EOS 5D and 30D, the Multi-Controller serves as the AF point selector. However,
with the EOS-1D Mark III, we concluded that it was best to use the Quick Control Dial or
Main Dial to select one of the 19 AF points. The Multi-Controller serves as a supplemental
camera control for the digital operation's UI. If you press the AF point selection button
and then press the Multi-Controller, the center AF point/automatic AF point selection can
be made. Any other AF point (other than center AF point) cannot be selected.
