Panasonic S 18-40mm f/4.5-6.3 Lens, Full-Frame, Autofocus, filter 62 mm (Front) - L-Mount

Touted as the world's smallest and lightest full-frame zoom lens, the 5.5 oz, 1.6" long Panasonic Lumix 18-40mm f/4.5-6.3 Lens brings high resolution from corner to corner in a unique zoom range for a flexible, versatile, carry-around lens.
Suitable for landscapes, buildings, and snapshots with a natural perspective, the lens also provides subtle bokeh when shooting subjects with the maximum aperture and at the minimum focusing distance of 5.9".
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.
