The 100mm T2.9 1.6x Full-Frame Anamorphic Lens from Sirui creates strong background compression, rich detail, cinematic bokeh, and artistic lens flairs suitable for up to 8K full-frame capture. This longer, 100mm T2.9 lens produces a shallow depth of field with a distinct focus falloff. Its anamorphic design produces an oval bokeh and horizontal blue streaks, giving your footage a dreamy or science fiction aesthetic. An image captured in 16:9 is de-squeezed to an anamorphic 2.8:1 aspect ratio. The 100mm prime features a female 1/4"-20 thread compatible with many lens supports, and its focus and aperture rings are uniformly geared like the other lens in the series for use with a follow focus and lens control system.
