Shrinking the sensor modules dimensions raised a new challenges for the auto-focus actuators. Nowadays, voice coil motors and piezzo motors are the main technologies used.

Both of them a having advantages and some drawbacks, we had a comprehensive experience on both technologies in terms of production quality and driving methods to achieve the best in terms of performance and accuracy.

Proved with AF motors from vendors like Sharp, KMOT, Toshiba, Samsung and others, MMS technology can guarantee stable operation in all working conditions and excellent focus accuracy and speed.
