The LUMIX S 18mm F1.8 is comprised of thirteen lens elements in twelve groups including three aspherical lenses, three ED (Extra-Low Dispersion) lenses, one UED (Ultra Extra-Low Dispersion) lens and one UHR (Ultra High Refractive Index) lens. The use of three aspherical lenses realizes both high descriptive performance and beautiful bokeh, which are common advantages to the series of all F1.8 lenses. The three ED lenses effectively suppress chromatic aberration. It is suitable for versatile situations including landscapes, astrophotography and architecture photography taking advantage of the ultra wide angle of view. It can also be used for close-up shots thanks to the minimum focusing distance of 0.18m.
The S-S18 also excels in video recording performance with a mechanism that suppresses focus breathing, together with a micro-step aperture control for smooth exposure change for recording professional quality video.
