Cinematic Anamorphic Lens for Super35

The Sirui 40mm T1.8 1.33X S35 AF Anamorphic Lens delivers a 2.35:1 aspect ratio on Super35 and APS-C sensors using its 1.33x horizontal squeeze. Its 16 elements in 12 groups provide professional sharpness while the T1.8 aperture excels in low light. An STM step motor enables fast, accurate autofocus and eye focus for efficient run-and-gun shooting.

Filmmakers Wanting Autofocus Anamorphic

This lens suits videographers who need autofocus speed with genuine anamorphic character including blue flare and oval bokeh. It is not for photographers who only shoot stills without desqueezing workflows. Buyers requiring full-frame coverage without crop mode should look elsewhere.

Verify Mount and Sensor Compatibility

Confirm your camera uses Sony E, Nikon Z, Fujifilm X or Micro Four Thirds mount before ordering. Ensure the body supports Super35 or APS-C crop mode to utilise the 1.33x squeeze correctly. Check that your editing software can desqueeze 2.35:1 footage for final output.

Questions about this item

Which Sony E-mount cameras can use this 40 mm T1.8 anamorphic lens without vignetting?

The lens covers Super 35 and APS-C sensors with a 1.33x squeeze, so it works on any Sony E-mount body using those formats; full-frame cameras will need crop mode.

Will the STM autofocus motor drive fast enough for run-and-gun shooting with my existing Sony APS-C body?

The built-in STM step motor delivers quick, accurate autofocus and eye-focus tracking, making handheld video and stills practical compared with manual-focus anamorphic designs.

How can I confirm the 1.33x squeeze is producing the correct 2.35:1 aspect ratio after mounting?

Shoot 16:9 footage, then check that horizontal oval bokeh and blue flare streaks appear, and verify the desqueezed frame measures 2.35:1 in your NLE or monitor.
