Description Description A bright wide-angle prime, theXF 14mm f/2.8 RfromFUJIFILMis a 21mm-equivalent lens featuring a broad angle of view well-suited for landscape, interior, and astrophotography applications. Its optical design incorporates a pair of aspherical elements to control distortion and spherical aberrations, and three extra-low dispersion elements are also featured, which help to reduce color fringing for improved clarity. A Super EBC coating is used, too, to reduce flare and ghosting for improved color accuracy and contrast when working in bright and backlit situations. Details Wide-angle prime lens is designed for APS-C-format FUJIFILM X-mount mirrorless cameras and provides a 21mm equivalent focal length. Bright f/2.8 maximum aperture balances a compact design with lens speed for working in difficult lighting conditions and is also suitable for astrophotography applications. Two aspherical elements limit distortion and spherical aberrations in order to realize greater sharpness and accurate rendering. Three extra-low dispersion elements greatly reduce color fringing and chromatic aberrations in order to produce greater clarity and color accuracy. Super EBC coating has been applied to individual elements to reduce lens flare and ghosting for improved contrast and color fidelity when working in strong lighting conditions. Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
