The flash coverage can be set to match the lens focal length from 
24mm to 105mm. The flash coverage can be set automatically or 
manually. Also, with the built-in wide panel, the flash coverage will be 
compatible with ultra wide-angle lenses as short as 14mm.

 Setting the Flash Coverage and Using the Wide Panel
Using the Wide Panel
If you set the flash coverage manually, make sure it covers the lens focal 
length so that the picture will not have a dark periphery.
 
The flash coverage will not be compatible with the EF15mm f/2.8 
Fisheye lens.
 
For the effective lens focal length (or crop factor), refer to the camera’s 
instruction manual.
 
If you use bounce flash with the wide panel in place, the entire display on 
the LCD panel will blink as a warning. Since the subject will be 
illuminated by both the bounce flash and direct flash, it will look 
unnatural.
 
Pull out the wide panel gently. Using excessive force may detach the 
wide panel.
