Sirui 75mm 1.33x Anamorphic – manual anamorphic cinema lens with 75mm focal length, f/1.8 aperture, and 1.33x squeeze ratio for APS-C and Super 35 sensors.

Overview

The Sirui 75mm 1.33x Anamorphic (model designation Sirui 75mm f/1.8 Anamorphic) is an anamorphic prime lens from the Chinese manufacturer Sirui. It belongs to the affordable 1.33x APS-C series, making it a camera lens for photo and video systems with interchangeable mounts, rather than lighting or grip equipment.

The anamorphic factor of 1.33x horizontally compresses the image during recording. When the recorded footage is de-squeezed in post-production, a wide, near-Cinemascope aspect ratio of approximately 2.40:1 is created from a 16:9 sensor crop. Characteristic of anamorphic optics are the oval bokeh and horizontal streak flares; Sirui offers the lens in variants with blue and neutral flares.

On-Set Usage

The lens is purely manual: focus and aperture are set by hand on the lens; there is no electronic aperture control and no image stabilization. The non-rotating front and the 67mm thread facilitate the use of filters and matte box adapters.

  • Within the Sirui 1.33x series, 75mm is among the longer focal lengths and is suitable for close-ups and portraits with an anamorphic image effect.
  • For correct geometry, the footage must be horizontally de-squeezed by a factor of 1.33 in post-production.
  • As the lens is designed for APS-C/Super 35, vignetting may occur on full-frame sensors; it is typically operated in APS-C/crop mode.

Perspectives

Cinematographer

Das Sirui 75mm 1,33x ist mein bevorzugtes Objektiv für intime Porträts und enge Nahaufnahmen mit anamorphem Look. Die Teleobjektiv-Brennweite komprimiert den Raum auf cineastische Weise, während die ovalen Bokeh-Kreise und horizontalen Flares die emotionale Tiefe verstärken. Für Close-Ups und emotionale Moments ist dieses Objektiv unschlagbar.

Director

Mit der 75mm 1,33x kann ich meine Schauspieler auf cineastische und schmeichelhafte Weise filmen. Die Teleobjektiv-Perspektive schafft Intimität und emotionale Nähe. Der anamorphe Look mit den subtilen Effekten verleiht intensiven Momenten eine zusätzliche visuelle Kraft, die die Story unterstreicht.

Producer

Das Sirui 75mm 1,33x erweitert die Möglichkeiten des Serien-Sets für Close-Up-Aufnahmen und emotionale Szenen. Die Teleobjektiv-Option würde bei Premium-Systemen zu erheblichen Zusatzkosten führen, während diese Sirui-Option das Budget schont. Dies ist eine wirtschaftlich intelligente Investition.
