C.Fn-05-1:Convenient when you want to check the depth of field. (p.28)
EOS digital cameras have one of three image sizes. The lens’ effective
focal length will differ depending on the camera’s image size. The
Speedlite automatically recognizes the EOS digital camera’s image size
and automatically sets the flash coverage for lens focal lengths from
24mm to 105mm.
When the Speedlite is attached to a compatible camera, <s> will
appear on the Speedlite’s LCD panel.
