Key Features
Designed for the FUJIFILM G-mount GFX camera system, the GF 20-35mm f/4 R WR Lens is a wide-angle zoom offering a 16-28mm equivalent focal length range. Covering ultra-wide to wide-angle perspectives, this zoom is particularly well-suited to landscape, travel, and architecture applications, and the constant f/4 maximum aperture maintains consistent performance throughout the zoom range. A sophisticated optical design pairs a trio of aspherical elements with one aspherical ED element and three ED elements to control both spherical and chromatic aberrations for improved sharpness, clarity, and color accuracy. Balancing the optical assets is an internal focusing mechanism that utilizes a linear AF motor to deliver quick, quiet, and precise focusing performance. A fluorine coating has also been added to the front element to repel moisture and the lens also features a dust-, freeze-, and weather-resistant construction for use in inclement conditions. Additionally, a manual aperture ring is featured for intuitive, tactile adjustment over exposure settings, and a Command position can also be set for camera-based control over the aperture.
Ultra-wide to wide-angle zoom offers a 16-28mm equivalent focal length to suit working in a variety of situations.
Constant f/4 maximum aperture affords consistent performance throughout the zoom range.
Three aspherical elements are featured in the optical design to control spherical aberrations for improved sharpness with Minimal distortion. Also, three extra-low dispersion elements and one aspherical ED element are also used to reduce color fringing and chromatic aberrations throughout the zoom range for increased clarity.
An internal focusing mechanism is controlled by a linear AF motor for smooth, silent, and fast focusing performance.
The front element features a hydrophobic fluorine coating to repel moisture.
Dust- and weather-sealed physical construction enables working in harsh climates and temperatures as low as 14°F.
Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
