- High speed and smooth operation with newly developed SDM (Supersonic Direct-drive Motor) equipped with high torque ring type ultrasonic motor
- Developing as an AW (All Weather model) this lens features a dependable dustproof, weather-resistant structure to prevent the intrusion of water and dust into the lens interior.
