The NIKKOR Z 135mm f/1.8 S Plena from Nikon brings unprecedented image quality in a popular focal length to the company's mirrorless Z System. The painterly Plena produces edge-to-edge clarity with otherworldly, circular bokeh across the entire frame for extraordinary results in portraiture, still-life photography, and cinematic video. The 135mm f/1.8 S Plena lens is the first NIKKOR Z lens to fully realize the mount's light-gathering potential. Drastically reducing vignetting, the clear path of light through the lens with minimal refraction is what produces the exquisite and regular round bokeh that distinguishes the Plena. The optical design also benefits image clarity. Like the bokeh effects, the lens achieves outstanding results across the whole frame. In strong lighting and backlit conditions, ARNEO and Nano Crystal Coats work against both axial and lateral chromatic aberrations to prevent ghosting, reflections, and flare to realize improved contrast and clarity. This system uses dual STM stepping motors, which offer impressively smooth and quiet autofocus performance that is well-suited to both stills and video applications. The Plena was designed with cinematographers in mind, beginning with the lens' popular focal length that lends itself to background separation and arms-length intimacy. The optical design has a direct result on the lens' satisfying, all-metal construction, creating a lighter-weight, carry-around lens that will take 82mm filters. The lens is additionally customizable with a clickless control ring that adjusts aperture, ISO, and exposure compensation, and an easily-reached assignable Fn button.
