Sirui’s New Astra 1.3x Anamorphic Lenses

credits: Sirui

Sirui has introduced Astra, a new line of 1.33x full-frame anamorphic lenses that come with autofocus, something we haven’t seen before in full-frame anamorphics. The lineup starts with three focal lengths, 50mm T1.8, 75mm T1.8, and 100mm T1.8. All three share the same exterior design, use 67mm front threads, and weigh between 600 and 700 grams (roughly 21–25 ounces). The lenses cover a 44mm image circle and all have 72mm outer diameters, plus dust- and drip-resistant construction.

Inside, the lenses use a 1.33x squeeze, which on a full-frame sensor desqueezes to a 2.39:1 aspect ratio. Sirui also emphasises the uniform T1.8 aperture across the set, giving you a consistent look and enough light for both low-light work and shallow depth-of-field shots. Autofocus, as mentioned is a big part of the Astra pitch, the motors support smooth and reasonably quick AF for handheld or gimbal setups, but users can switch to manual focus at any time. The MF rings include marked distance scales and are compatible with follow-focus units and LiDAR setups.

The lenses are available in Sony E, Nikon Z, and L-Mount, with two flare options, blue or neutral, depending on the look you want. Early-bird pricing through Kickstarter is $799 per lens or $2,399 for the full three-lens set, which also includes a custom case. Once the campaign wraps up, standard pricing will be $999 per lens or $2,999 for the set.
