Sirui 40mm T1.8 1.33x S35 Autofocus Anamorphic Lens (Sony E, Blue Flare)

Cinematic Look with Autofocus Convenience

The Sirui 40mm T1.8 1.33x S35 Autofocus Anamorphic Lens offers a distinctive cinematic look with the practicality of autofocus. Designed for Super35/APS-C sensors, it delivers a 2.35:1 aspect ratio when shooting in standard 16:9, thanks to its 1.33x anamorphic squeeze. The STM motor enables fast and accurate autofocus, while a manual override and dedicated AFL button provide flexibility for complex shooting scenarios.

Built for Super35 and Sony E-Mount Systems

Optimized for Super35 coverage, this lens mounts directly to Sony E cameras without the need for adapters. It supports electronic communication with the camera, enabling EXIF data transfer and firmware updates via a USB-C port. Its 40mm focal length is ideal for portraits, street scenes, and cinematic wide shots, translating to approximately 42mm in full-frame equivalent.

Striking Visual Effects

This blue flare version creates bold horizontal flares that evoke a classic sci-fi aesthetic. The fast T1.8 maximum aperture allows excellent low-light performance and beautiful bokeh, while its 11-blade iris can render both hexagonal and oval background blur depending on your aperture setting. One aspherical and five cylindrical elements ensure minimal focus breathing and controlled chromatic aberration.

Professional Build, Compact Design

Despite its cine-focused design, the lens remains compact and lightweight at just 614g, making it suitable for gimbal or handheld shooting. It features an 80mm front diameter, a 77mm filter thread, and industry-standard 0.8 MOD focus and aperture gears. The 360° focus rotation provides precise control for both automated and manual use.

This lens blends modern autofocus features with vintage anamorphic aesthetics in a form factor that fits into any indie filmmaker’s kit. Whether you’re capturing dramatic narratives, music videos, or stylized content, the Sirui 40mm blue flare delivers a unique and professional image without breaking the bank.
