Smallest and Lightest Full-Frame Zoom Lens
The lens achieves its high sharpness and small form factor with the help of an optical design featuring three aspherical elements, two extra-low dispersion elements, and one ultra-high refractive element. Used with the Lumix S9's Hybrid Zoom function, the lens can achieve a zoom range of 18-120mm. The lens also benefits video shooters by suppressing focus breathing. In addition to its lightweight and portable design, the lens' construction is dust, splash, and freeze-resistant for use in adverse weather conditions. The front element also has a fluorine coating to repel water, oil, and other debris.
