Abstract
A lens is positioned to be received by a lens holder. The lens includes a first electrical trace and the lens holder includes a second electrical trace. The first and second electrical traces form electrodes of a sense capacitor. A capacitance of the sense capacitor is sensed. From the sensed capacitance, a determination is made as to whether the lens is present and properly positioned in the lens holder.
