* If the TTL auto mode is selected, these flash units can
be used for daylight-sync shooting, because the shut-
ter speed is adjusted according to the ambient bright-
ness. The slower shutter speed varies according to
the lens focal length. However, when a non-autofocus
lens is in use or the Action Program Mode is in use,
the shutter speed is set to 1/100 of second. The ap-
erture value will also be fixed but is changed depend-
ing on what ISO film is loaded.
