The Nikon NIKKOR Z 35mm f1.8 S Lens is ideal for portrait and close-up shots. It can be fitted to Nikon Z-mount mirrorless camera systems. The lens structure has 11 optical elements in 9 groups. Among these elements there are two ED and three aspherical lenses to minimize both chromatic and spherical aberrations. The nanocrystal and super integrated coatings improve clarity and image saturation by reducing ghosting and flare. The stepping AF motor ensures your subject doesn39t get distracted when fixing the focus point on it. With the rounded 9-blade diaphragm the lens provides purely circular bokeh in the out-of-focus background. The programmable control ring not only lets you manually override the focus but also allows you to adjust the aperture and exposure compensation. A fluorine coat is applied to the top element to resist fingerprints dust and moisture. Also the lens barrel is dustproof and waterproof to hold itself in inclement weather.
