A weather-sealed design at just 170g and a fast, quiet stepping motor AF system make this 53mm-equivalent prime an unobtrusive everyday lens. Its optical formula with two aspherical elements delivers high sharpness, while the 9-blade diaphragm produces smooth bokeh for subject separation. This lens is best for street and travel photographers needing a discreet, all-weather normal field of view on Fujifilm X-mount bodies.
