Hans ............. is this to imply that the F280 takes daylight into
account as a continuing source of light and opposed to it [the F280]
reacting to the intensity of the daylight at the instant it [the F280]
fires? If the former I can understand that the sudden impulse of light
from the Vivitar might cause a problem but if the latter surely isn't
the impulse of light from the Vivitar's flash just another source of
directional light the F280 has to account for when "doing its thing"?
I will some experimentation and report back shortly.
