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. Leveraging the Z-series' larger mount diameter, 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 lens' larger rear element enables this leap in peripheral illumination, bringing consistent brightness to the extreme edges of the frame. 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. A short-wavelength refractive front element, an aspherical element, and four extra-low dispersion elements all contribute to minimizing color bleeding, fringing, and flare. The lens also excels at transitions between zones of focus, which, when combined with the lens' resolving power, produce eye-popping subject separation and textural detail at the widest aperture. 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. In addition to the lens' stunning imagery, the Plena also features smooth aperture transitions and natural shifts between focus positions. 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.
