The MTF chart for the Nikon NIKKOR Z 35mm f/1.8 S shows exceptional flatline performance wide open at f/1.8 cross the entire field, excepting the extreme corners which drop off slightly. Overall contrast for coarse structures looks to be world class—an important characteristic for a 3D lifelike feel.
