Panasonic LUMIX S 14-28mm F4-5.6 Macro Lens

The Panasonic LUMIX S 14-28mm F4-5.6 Macro Lens is a new lightweight ultra wide-angle zoom lens that weighs in at a compact 345 grams, while boasting impressive macro capability with a magnification of 0.25x (at 14mm) - 0.5x (at 28mm).
The wide angle of view supports landscape shots and is also suitable for solo content creators filming themselves at arm’s length. A rugged dust/splash-resistant design ensures reliable field use in challenging conditions and temperatures down to -10 degrees Celsius. In addition, the front lens element has a fluorine coating to repel liquids such as water or oil. An ND/PL filter with 77mm diameter can be attached.
The LUMIX S 14-28mm F4-5.6 MACRO is comprised of fourteen lens elements in ten groups including one aspherical ED (Extra-Low Dispersion) lens, one aspherical lens, three ED (Extra-Low Dispersion) lenses and one UHR (Ultra High Refractive Index) lens. The use of aspherical lenses realises beautiful bokeh, while the ED lenses effectively suppress chromatic aberration.
The lens offers silent, high-precision autofocus. For the non-linear setting, focus is shifted with a variable amount according to the rotation speed of the focus ring; while for linear setting focus is shifted with a designated amount according to the rotational quantum of the focus ring. Sensitivity (the amount of focus shift per rotational quantum) can be selected from 90 to 360 degrees. The lens also incorporates a mechanism that suppresses focus breathing and micro-step aperture control for smooth exposure changes during recording.
