Description and Reviews
From Sirui:
EXPANSIVE PERSPECTIVE S35 AUTO FOCUS ANAMORPHIC LENS. Traditional anamorphic lenses often struggle with quick focus acquisition due to the lack of autofocus. The SIRUI 20mm T1.8 1.33x anamorphic lens, equipped with an STM stepping motor, delivers fast, accurate, and smooth autofocus.
With a horizontal field of view equivalent to a 22mm full-frame lens, this wide-angle lens captures expansive landscapes, breathtaking starry skies, and tight indoor spaces with ease.
With a constant 1.33x squeeze factor, this lens delivers a stunning 2.35:1 widescreen cinematic aspect ratio in 16:9 mode, maximizing sensor utilization for a truly immersive viewing experience.
Fast T1.8 aperture makes sure more light enters the sensor so that it can reduce ISO and deliver a pure night scene. Even in low-light situation, you can get outstanding image with sharp subject, blurred background and soft bokeh.
