True Exposure is an HC/HCD lens function that allows the
shutter speed to remain un-affected when stopping down.
This effect is perhaps not so commonly understood as it is
restricted specifically to integral lens shutters as opposed to
focal plane shutters.
When a lens is stopped down, the effective shutter speed
becomes longer, consequently affecting the set exposure.
At slow shutter speeds the effect is minimal but at faster
speeds, e.g. 1/500s, the effect becomes clearly visible. As
Hasselblad knows exactly how the shutters behave in HC
lenses, automatic compensatory measures in speed setting
adjustments are therefore employed.

As compensation can only be put into effect where speeds
can be adjusted, this prevents the possibility of adjusting
the fastest speed of 1/800s. To counter this, compensatory
adjustments are therefore made to the aperture instead to
retain the set exposure.
However, this compensation is not always required and
when using flash/strobe as the main light source it is actually
undesirable because compensation will result in underex-
posure. Therefore, when using flash/strobe as the main light
source, you should set True Exposure to OFF in Custom
Options #13 on grip.
