Sirui Expands Its Full-Frame Aurora Lineup With Fast 15mm f/1.6 and 24mm f/1.4 Primes

Sirui just added two new additions to its full frame autofocus Aurora lens lineup: the Aurora 15mm f/1.6 ultra-wide lens and the Aurora 24mm f/1.4 wide angle lens. Living up to the Aurora foundation, both lenses combine bright maximum apertures, STM autofocus performance, and dedicated video-friendly ergonomics for hybrid creators.

Ultra-Wide Field With Built-In Distortion Control

Optically designed for architectural photography, tight interior spaces, vlogging, and low-light night scenes, the Aurora 15mm f/1.6 pairs a 15mm ultra-wide perspective with a bright f/1.6 maximum aperture. The fast aperture provides improved light gathering in dim environments, allowing creators to shoot handheld without relying on higher ISO settings or slower shutter speeds.

Key Highlights and Optical Design

• Optical Geometry Control: SIRUI designed the 15mm optical layout specifically to suppress straight-line barrel distortion and edge stretching typical of ultra-wide optics. This design minimizes the need for heavy digital software correction and cropping in post-production.
• Standard 77mm Front Filter Thread: Unlike many ultra-wide full frame primes featuring bulbous front elements that require rear gel slots or specialized filter holders, the 15mm f/1.6 features a standard 77mm front thread for standard screw-in ND and CPL filters.
• Low-Light Performance: The fast f/1.6 optics support low-light photography, astrophotography, and handheld interior work.

A Versatile Wide Prime Built for Hybrid Workflows

The Aurora 24mm f/1.4 provides a versatile wide angle perspective that captures environmental context while keeping subjects naturally proportioned, offering a wider field of view than a 35mm without the exaggerated perspective of ultra-wide lenses. With its bright f/1.4 aperture, the lens offers strong low-light performance alongside precise depth-of-field control, making it well-suited for interviews, weddings, documentary work, commercial video, and run-and-gun shooting.

Key Highlights and Video Integration

• De-Clickable Aperture Ring: Includes an integrated aperture ring that switches between tactile clicked detents for stills and smooth, stepless rotation for continuous exposure transitions during video recording.
• Suppressed Focus Breathing: Engineered to minimize framing shifts during focus transitions, ensuring stable framing during focus racks.
• Subject Isolation: The f/1.4 aperture enables subject separation and shallow depth-of-field effects in environmental portraiture and cinematic video.

Pricing and Availability

The SIRUI Aurora 15mm f/1.6 is priced at $599, while the SIRUI Aurora 24mm f/1.4 is priced at $499. Both lenses will launch initially in Sony E and Leica L mounts in 2026, with Nikon Z and Fujifilm X mounts scheduled for Q1 2027.
