XF 23mm f/2 R WR from FUJIFILM is a versatile 35mm-equivalent lens characterized by its f/2 maximum aperture that strikes and ideal balance between portability and speed. The optical design features two aspherical elements to reduce distortion and spherical aberrations in order to produce greater sharpness and accurate rendering. A Super EBC coating is also used to control flare and ghosting for improved contrast and color fidelity when working in bright and backlit conditions. Complementing the optics is a stepping motor, along with an internal focusing design, which provides quick and especially quiet focusing performance. Additionally, the lens is weather-sealed to suit working in inclement conditions.
