SIRUI Astra T1.8 1.33x Full Frame Autofocus Anamorphic Cine Lenses 100mm - Sony E - Blue Flare

The SIRUI Astra 100 mm T1.8 brings autofocus to full-frame anamorphic filmmaking, pairing a consistent 1.33x squeeze with a fast cinema aperture. Its perspective suits close-ups, intimate dialogue and compressed telephoto compositions, and this Sony E version has a blue streak flare character.Anamorphic framing and flare characterThe constant 1.33x squeeze records a wider horizontal perspective than a spherical lens of the same focal length. When the footage is de-squeezed in post-production, it takes on an approximately 2.35:1 widescreen character from 16:9 capture, together with the elongated bokeh and visual depth associated with anamorphic optics.Autofocus and practical cine handlingThe T1.8 aperture is useful for controlled background blur and available-light scenes. An STM-driven autofocus system and AF/MF switch make the lens practical for independent productions, while cine-oriented focus and aperture controls allow more deliberate operation when needed. The blue flare version is designed for Sony E minimum focus is 0.70 m.SIRUI uses five cylindrical optical elements in the 100 mm model. Its longer focal length increases subject isolation and works well for close-up storytelling where the background should remain present but visually subdued.Key featuresFull-frame coverage and constant 1.33x anamorphic squeeze100 mm focal length for storytelling and detailed framingFast T1.8 maximum apertureSTM autofocus with AF/MF switch67 mm filter thread and common cine gear positionsMinimum focusing distance: 0.70 mBlue flare renderingSony E mountWhat's in the boxAstra 100 mm T1.8 1.33x anamorphic cine lensFront and rear lens capsManufacturer warranty card
