A staple of wide-angle versatility, the Lumix S PRO 16-35mm f/4 from Panasonic is an L-mount wide zoom featuring an f/4 constant maximum aperture. An optimized optical design incorporates a series of aspherical, low dispersion, and high refractive index elements, to control a variety of aberrations, color fringing, and distortion for sharp, clear, well-corrected imagery throughout the zoom range. Complementing the optics is a unique double-magnet linear motor focus system, which provides high-speed response and power while remaining compact in size. The lens also sports a rounded nine-blade diaphragm, which contributes to the quality of bokeh, and a weather-sealed construction to suit working in a variety of weather conditions.

Wide-angle zoom is designed for full-frame L-mount mirrorless cameras, however can also be used with APS-C models where it provides a 24-52.5mm equivalent focal length range.

Constant f/4 maximum aperture maintains consistent illumination throughout the zoom range.

Three aspherical elements and one ultra-high refractive index element help to minimize distortions and spherical aberrations throughout the zoom range in order to maintain edge-to-edge sharpness and illumination.

One extra-low dispersion element greatly reduces chromatic aberrations and color fringing in order to produce a high degree of clarity and color accuracy.

The autofocus focus system employs both a double-magnet linear motor to deliver impressively fast and precise focusing performance while remaining compact. A focus clutch mechanism has also been incorporated, which allows for near-instant AF/MF switching.

Splash, dust, and freezeproof design benefits working in inclement weather conditions down to -14°F.

Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
