慢快門閃燈 is only need in nikon

canon aways can do but no need to set
basically is defaut!!

慢快門閃燈
is meaning can do some flash mode in lower than a 1/60 shutter speed

canon aways can do lower than 1/60 shutter speed in a-mod

Manual Control (Shutter and Aperture), can select lower shutter speed
with ETTL flash

My 580EXII Flash always in E-TTL mode
