Custom Functions
How to refine your camera’s performance
It’s fair to say that EOS digital cameras have evolved considerably since the launch of the EOS D30 in 2000. Back then, a 3.1MP APS-C CMOS sensor and three AF points were cutting edge. But even with its modest specification by today’s standards, the camera performance and operation could still be fine-tuned via Custom Functions in the menu.
Today’s Canon EOS cameras offer a similar set of Custom Functions, although given their additional functions and advanced performance, models such as the EOS R6 Mark II and EOS 5D Mark IV come with multi-tabbed menus of customizable adjustments.
A number of these functions are those which you’d perhaps set and forget when you first get the camera. For example, some models have a Custom Function that allows you to change the direction of the dials as you’re making adjustments when you’re shooting in Av or Tv mode. While the majority of us are likely to stick with the default set-up, you can reverse the direction that the dials are turned to adjust the shutter speed or aperture.
