Product details

The SIRUI 20mm T1.8 AF Anamorphic Lens is a highly advanced cine lens specifically designed for Sony E-Mount cameras. With a constant 1.33x squeeze, it allows for stunning shots in the 2.35:1 widescreen format, making it ideal for filmmakers and videographers seeking cinema-quality imagery. The large aperture of T1.8 provides a shallow depth of field and excellent low-light performance, opening up creative possibilities in image composition. The lens weighs approximately 480 g, making it a practical choice for flexible use, even in combination with gimbals. Its construction features 16 elements in 12 groups, including special cylindrical and aspherical lenses that help minimize distortion and enhance image quality. The SIRUI 20mm T1.8 is therefore an excellent choice for anyone looking to achieve professional results in film production.

  • Autofocus support via STM motor
  • Minimum focusing distance of 0.4 m
  • 11 aperture blades for elliptical bokeh
  • 360° focusable range
