A liquid lens can tilt a fluid interface, such as for optical image stabilization or off-axis focus. Tilting the interface can cause coma aberration or other dynamic wavefront error. The liquid lens can be driven to reduce the coma aberration or other dynamic wavefront error. For example, input shaped signals can be used. In some cases, the signals can be overdriven and/or underdriven, which can increase response time, and/or encourage settling of the interface.
