One of the thing that distinguishes the Canon 7D, from most of the other cameras, is the customization. So many that it’s unbelievable, I’m not sure that I’ve recovered from it.

There are 4 types of custom functions:

  1. Exposure settings
  2. Image settings
  3. Auto-Focus settings & Drive settings
  4. Others, the grab bag
