The Nikon NIKKOR Z 24ndash70mm f4 S Lens maintains a consistent optical performance throughout the zoom range. It is made for the Nikon Z series mirrorless cameras. The lens uses an optical construction of 14 elements in 11 groups which includes aspherical and Extra-low Dispersion elements to reduce chromatic and spherical anomalies. Both nanocrystal and super integrated coatings are applied to the lens elements to suppress internal reflections and enhance clarity in bright conditions. The stepping motor shifts between different focus points without making any noise. You may also manually override the autofocus at any point. The rounded 7-blade electromagnetic diaphragm produces circular bokeh in the background. With the programmable control ring you can adjust the aperture and exposure compensation settings. The front element has a fluorine coat that keeps its safe from dust and moisture. Also the dust- and moisture-resistant lens barrel allows working in challenging weather conditions.
