SIGMA LBA-708 - Manual (Page 104)

Notice: Some cameras suffer a reduced operating dynamic range when very short exposure times are employed.
This can be seen as a dramatic change in the camera baseline or as a reduction in the camera’s saturation level. If
your camera reacts in one of these ways you may find that the AutoExposure technique will fail to yield optimum
results.
