The black XF 50mm f/2 R WR offers a 76mm equivalent focal length to suit a variety of applications, including portraiture and still lifes. The lightweight design and bright f/2 maximum aperture benefit working in low-light conditions and also afford a high degree of control over the depth of field for selective focus techniques. The optical design features one aspherical ED element, which controls distortion and color fringing for sharper, clearer results throughout the aperture range. 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. Bright f/2 maximum aperture benefits working in difficult lighting conditions and also offers greater control over the depth of field. 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. The lens body incorporates weather sealing to protect against dust and moisture, and to enable worry-free use in inclement conditions and freezing temperatures as low as 14°F.
