Sirui 40mm T1.8 1.33X S35 AF 40mm
Combining a fast T1.8 aperture with a 1.33x anamorphic squeeze, this lens delivers a 2.35:1 widescreen image and strong low-light performance directly in-camera. Its integrated STM autofocus supports eye tracking and subject detection, while the 614g build keeps it practical for gimbal and run-and-gun use. This lens is best for Nikon Z-mount filmmakers who want accessible, authentic anamorphic character without manual focus rigs.
