Nikon Z System. This Sirui 50mm T2.9 Anamorphic 1.6x was designed specifically for cameras in Nikon’s full-frame Z-mount system. Z-mount lenses only work with Z-mount cameras, and Z-mount cameras are only compatible with Z-mount lenses.

Cinematize Your Shots. The Sirui 50mm T2.9 Anamorphic 1.6x enlarges your horizontal field of view up to 60%, giving you a field of view equivalent to that of a wider 31mm spherical lens and letting you see well to the left and right of your subject. Images captured in 16:9 are de-squeezed to an anamorphic 2.8:1 aspect ratio, while images captured in 3:2 will de-squeeze to an anamorphic 2/4:1 image. Its focus and aperture rings are geared for use with follow-focus systems.

Distinctive Cinematic Effects. This lens’s optical design and nano coatings produce dreamy-looking horizontal blue streaks with very little stray light, which Sirui calls “Sci-Fi Horizontal Flares.” The 50mm T2.9 uses its ten aperture blades to produce oval bokeh with shallow depth of field, which you can optimize with a turn of the aperture ring.

Advanced Optics. The 50mm T2.9’s thirteen-group/sixteen-element optical design includes German-manufactured Schott optical glass elements with super spectra coatings to create its ultra-wide rectangular aspect ratios, long horizontal lens flares, and oval bokeh.
