¡With TTL and A-TTL autoflash Speedlites (EZ-, E-, EG-, ML-, TL-
series) set in the TTL or A-TTL autoflash mode, the flash will be fired
only at full output. If you set the camera’s shooting mode to manual or
aperture-priority AE, you can adjust the aperture and fire the flash at
full output. Meanwhile, the Speedlite will remain in the TTL or A-TTL
autoflash mode.
¡When the 580EX or 550EX is set to C.Fn-03-1, the flash will always
be fired at full output even in the TTL autoflash mode.
