The NIKKOR Z 135mm f/1.8 S Plena brings together everything Nikon knows about producing an outstanding portrait lens for full-frame digital cameras. It enters a heavily contested market with fast autofocus, superb sharpness and contrast, and beautiful rendering of background blur. Bokeh is exceptionally well balanced with no distracting artifacts. This weather-sealed lens also performs very well for general photography, as well as serious video production. A pair of programmable function buttons is on board for those who wish to fine-tune the lens for their needs.
