Aero Bright Coating II and HD Coating on the 15 lens elements reduces flare and ghosting even when shooting in harsh lighting, and a front element SP Coating repels water and fingerprints from affecting the front of your lens. Autofocus is powered by Pentax's Ultrasonic Motor SDM, providing fast and accurate focus while shooting. Additionally, the rounded 9-blade diaphragm produces smooth bokeh for portraits or other types of shots. This lens is also weather sealed, ensuring consistent performance during adverse outdoor shooting conditions.
