A camera apparatus (10) has a zoom lens (12) having a zoom focus setting
that is adjustable over a range of focus values and control circuitry for
generating a variable voltage potential according to the zoom focus
setting. A flash illumination apparatus (20) has a light source (32) and
a variable focus liquid crystal lens (24), the variable focus liquid
crystal lens (24) having a first and a second solid optical element (40,
50), chamber (44), the two electrodes (42, 48) and liquid crystal
material (46). A variable voltage is applied to the liquid crystal
material (46) for the lens power according to the zoom focus setting.
