The Sirui T1.8 1.33X S35 camera lens is a 40 mm anamorphic prime lens with autofocus and manual focus. Its 1.33x squeeze creates a 2.35:1 aspect ratio when shooting in 16:9 mode. The STM motor supports fast, precise autofocus, while the lens switch lets you choose between autofocus and manual focus.
The maximum T1.8 aperture is suited to low-light shooting, while click and de-click aperture settings allow smooth exposure adjustment. The lens features one aspherical and five cylindrical elements, supports EXIF metadata transmission, and includes a USB-C port for firmware updates. It produces neutral flares and distinctive hexagonal or oval bokeh. The 80 mm front outer diameter, 0.8 MOD gears, and 360° focus rotation make it suitable for cinematic shooting.
