Fujifilm GF 20-35mm f/4 R WR - Fujifilm G Mount

The GF 20-35mm f/4 R WR is an ultra-wide-angle zoom lens for the Fujifilm GFX system, providing a 16-28mm equivalent focal range. Despite its wide coverage, it remains relatively compact and features an internal zoom design to maintain balance. The optical path includes three aspherical, one ED aspherical, and three ED elements to control distortion and flare. It is an essential tool for medium format landscape, architectural, and interior photographers. Used units should be inspected for the condition of the front element, as wide-angle lenses are prone to contact marks. The internal zoom should be smooth and silent. SDS technicians check for decentering, which can be more apparent in ultra-wide lenses, and verify the integrity of the weather sealing. Ensure the aperture ring clicks firmly into each position and that the mount shows no signs of excessive wear.
