The Viltrox AF 135mm f1.8 for Nikon Z is ideal for portraiture, delivering strong compression, edge-to-edge sharpness, and rapid, near-silent autofocus with a HyperVCM motor that's 150% faster than STM. A bright f1.8 aperture and 11-blade diaphragm produce soft, circular bokeh in low light. Dual Fn buttons, weather sealing, and nanocoated optics ensure reliability in both studio and outdoor environments.
