Sirui 20mm T1.8 1.33x Anamorphic vs Sirui Night Walker 35mm T1.2 Cine Lens

Buy the 20mm T1.8 if you need autofocus, a wide field of view, or true anamorphic widescreen framing. Buy the Night Walker T1.2 if you shoot manual and want the brightest aperture in the S35 set. The 20mm is the more specialized tool: an STM motor with eye tracking, a 1.33x squeeze and a 37mm image circle that covers S35 and nearly all full frame. The Night Walker is a conventional spherical lens with a faster T1.2, 12 blades and a 270-degree focus throw, and its 4.9 rating across 155 ratings shows owners are happy with the look and build.

• Choose the Sirui 20mm T1.8 1.33x Anamorphic if you want autofocus and eye tracking, a wide 20mm view, and 2.35:1 widescreen straight out of a 16:9 sensor.
• Choose the Sirui Night Walker T1.2 if you shoot manual, want the extra stop of light for low light and shallow depth of field, and prefer a matched S35 prime set.
