Product details

The SIRUI 20mm T1.8 Anamorphic Lens with MFT mount is a highly advanced cine lens specifically designed for filmmakers and videographers. With a constant 1.33x squeeze, it allows for stunning widescreen shots in a 2.35:1 format, making it ideal for creative projects that require a unique visual aesthetic. The aperture of T1.8 provides a shallow depth of field and excellent low-light performance, making it a versatile choice for various shooting situations. The lens weighs approximately 480 g, making it lightweight and easy to handle, allowing for seamless use with gimbals and other stabilization systems. The construction includes 16 elements in 12 groups, including cylindrical and aspherical lenses, which contribute to high image quality and a distinctive elliptical bokeh. The SIRUI 20mm T1.8 is therefore an excellent choice for anyone looking to achieve professional results in film production.
