H Setting The Flash Coverage And Using The Wide Panel - Canon Speedlite 430EX User Manual

H Setting the Flash Coverage and Using the Wide Panel

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.
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.
Using the Wide Panel
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.
