In the description of the new items marked high image quality, the use of three aspherical elements and eight glass elements with anomalous partial dispersion to reduce chromatic aberrations. For fast focusing lens has two stepper actuator so that the entire focusing range can be completed in just 250 milliseconds. Manual focus is done using the ring magnet and the sensor. The sensor detects the magnetic field changes when you turn the ring and transmits data for the operation of the actuator.
