Other Canon flashes
Canon flashes other than the Speedlite EX series will fire at their full strength. For
the optimal aperture values and ISO speeds for the distance to the subject, refer
to the guide number listed in the flash’s user guide.
• For continuous shooting, the flash can be used in quick flash mode (pilot
lamp lit green). In this case, flash output may be less than with full flash
(pilot lamp lit red) (580EX II only).

menu cannot be chosen (580EX II only).
