The SIRUI Astra 50 mm, 75 mm and 100 mm T1.8 full-frame anamorphic kit spans natural framing, portraits and telephoto detail with autofocus on each lens. The matched 1.33x squeeze and blue streak flare give the L-Mount set a coherent widescreen look across a production.
Anamorphic framing and flare character
The 1.33x squeeze expands the captured image horizontally after de-squeezing, creating a cinematic widescreen frame from a standard 16:9 recording. The T1.8 aperture supports available-light shooting and softly defocused backgrounds, while autofocus helps solo operators and smaller teams work quickly.
Autofocus and practical cine handling
This L-Mount set uses the blue flare treatment. Shared 67 mm filter threads, matched control layout and uniform optical rendering help keep lens changes efficient. Auto/manual focus switching and click/de-click aperture adjustment provide flexibility between controlled cinema takes and spontaneous video work.
SIRUI includes a protective safety case for the three-lens set. Similar colour, flare character and focus behaviour across 50 mm, 75 mm and 100 mm help keep a consistent look when filming dialogue and close-ups with different fields of view.
