SIRUI Astra T1.8 1.33x Full Frame Autofocus Anamorphic Cine Lenses 75mm - L-Mount - Blue Flare

The SIRUI Astra 75 mm T1.8 brings autofocus to full-frame anamorphic filmmaking, pairing a consistent 1.33x squeeze with a fast cinema aperture. Its perspective suits portrait scenes, interviews and selective detail framing, and this L-Mount 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 L-Mount minimum focus is 0.60 m.SIRUI specifies a 13-blade aperture for the 75 mm model. Together with the longer focal length and anamorphic optics, this supports rounded, stretched background highlights that work well in portraits and interview scenes.Key featuresFull-frame coverage and constant 1.33x anamorphic squeeze75 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: 0.60 mBlue flare renderingL-MountWhat's in the boxAstra 75 mm T1.8 1.33x anamorphic cine lensFront and rear lens capsManufacturer warranty card
