The Fujifilm FUJINON XF16mm F2.8 R Lens is best suited for the newly introduced Fuji X-T30 as well as other APS-C cameras in the X-series line up. Its optical design has 10 elements in 8 groups, including two aspherical glass lenses that reduce distortions occurring near the edges. A Super EBC coating is applied on the elements to minimize ghosting and flare. The stepping AF motor maintains a noise-free yet accurate autofocus performance. To complement the wide aperture of f/2.8, the lens uses a rounded 9-blade diaphragm that creates purely circular bokeh. The lens barrel has weather-resistant seals at critical points to keep dust and moisture at bay.
