Description

Sirui Astra T1.8 1.33x AF Anamorphic 3-Cine Lens Kit (Sony E, Neutral Flares)

The Sirui Astra T1.8 1.33x AF Anamorphic 3-Cine Lens Kit (Sony E, Neutral Flares) is a comprehensive cinema lens bundle engineered to deliver wide, widescreen cinematic imagery directly to modern full-frame mirrorless camera bodies. Combining three versatile focal lengths—50mm, 75mm, and 100mm—this kit features a constant 1.33x horizontal squeeze factor that captures a classic 2.4:1 aspect ratio on standard 16:9 sensors without cropping or resolution loss.

Uniquely equipped with fast autofocus capabilities and electronic communication, the lenses in the Sirui T1.8 1.33x AF Anamorphic 3-Lens Kit eliminate the absolute necessity of a dedicated focus puller while still retaining manual focus gear rings and metric/imperial scales for traditional production workflows. Operating at a fast T1.8 maximum aperture, each lens provides impressive low-light performance, shallow depth of field, oval background bokeh, and elegant neutral horizontal streak flares for a natural, controlled anamorphic character. Designed with an expansive 44mm image circle, every lens in the set delivers edge-to-edge sharpness with controlled breathing and uniform color matching across all focal lengths, making fast lens swaps seamless during production.
