About TTL and A-TTL Autoflash Speedlites

•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 550EX is set to C.Fn-03-1, the flash will be fired at full output even in the TTL autoflash mode.
