A unique zoom covering ultra-wide to short portrait-length fields of view, the Panasonic Lumix S 20-60mm f/3.5-5.6 is a sleek and versatile lens designed for full-frame L-mount mirrorless cameras. The distinct range of focal lengths is also complemented by flexible focusing capabilities, which permit working with subjects as close as 5.9″ with a 0.43x magnification for near-macro performance. In terms of optics, the lens incorporates a series of aspherical, high refractive index, and low dispersion elements to control a variety of aberrations and realize a high degree of clarity and sharpness. A fluorine coating has been applied to the front element to reduce smudging and make it easier to clean and then lens also features a weather-sealed design for working in harsh environmental conditions. Additionally, suiting both photo and video applications, a stepping motor is featured, which affords fast, precise, and near-silent autofocus performance.
