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-3-1, the flash will be fired at full output even in the TTL
autoflash mode.
