Lens Technology: Dual MPU (Micro-Processing Unit)

Dual MPU provides precise AF performance and consistent powerful VC image stabilization

Dual MPU is a micro processing unit incorporating two different microchips. Two separate processor units mean that digital signals from the VC image stabilization and autofocus are processed separately at maximum speed. This means, for example, that commands from the camera and AF motor can be interpreted at lightning speed and implemented precisely.
