Sirui Aurora 15mm f/1.6 & 24mm f/1.4 Lenses Announced: Fast Full-Frame AF Primes

Sirui has officially expanded its flagship autofocus prime lineup with the introduction of the Sirui Aurora 15mm f/1.6 and Sirui Aurora 24mm f/1.4. Designed for full-frame mirrorless camera systems, these ultra-wide optics join the existing 35mm f/1.4 and 85mm f/1.4 models to form a complete high-speed prime setup for landscape, astrophotography, architectural, and video creators.

The announcement follows a busy release schedule for the manufacturer, which recently introduced compact, budget-friendly options detailed in our Sirui Swift AF 20mm f/2.4 & 40mm f/2.2 Announcement coverage. While the Swift series focuses on ultra-lightweight portability under $150, the Aurora line prioritizes flagship optical performance, ultra-fast maximum apertures, and refined physical controls designed to handle demanding professional environments. To see how these compare with competing third-party optics, read our comprehensive Best Third-Party Lenses Guide.

Both new Aurora lenses feature all-metal weather-sealed construction with dust, stain, and splash resistance, alongside tactile physical controls including a customizable Fn button, AF/MF switch, an Iris Lock switch, and a switchable clicked/de-clicked aperture ring. Autofocus across both models is driven by a quiet Stepper Motor (STM) system supporting real-time eye tracking and subject detection.

Sirui Aurora 15mm F1.6: Ultra-Wide Reach & Low Distortion

The Aurora 15mm f/1.6 delivers an expansive 109.3-degree diagonal field of view on full-frame sensors while placing heavy emphasis on optical geometry. Sirui engineered the optical path to hold barrel distortion to an ultra-low 1.4%, keeping straight lines natural across the frame for architectural and interior scenes. Crucially for landscape and astro photographers, the 15mm f/1.6 accepts standard 77mm front screw-in filters despite its extreme wide-angle field of view.

• Optical Construction: 17 elements in 12 groups, including 3 aspherical elements, 3 Extra-low Dispersion (ED) elements, and 3 High-Refractive-Index (HRI) elements.
• 11-Blade Aperture Diaphragm: Produces smooth, natural background roll-off and attractive point-source highlights.
• Minimum Focus Distance: Focuses down to 0.3 meters (11.8 inches) for dramatic wide-angle close-ups.
• Dimensions & Weight: Measures 82 × 106.4 mm, weighs approximately 540g (varies slightly by mount), and takes 77mm front filters.

Sirui Aurora 24mm F1.4: Fast Aperture for Street & Astrophotography

The Aurora 24mm f/1.4 offers a classic wide-angle perspective paired with a bright f/1.4 maximum aperture, making it ideal for environmental portraits, low-light street work, and night cityscapes. The fast aperture allows for high shutter speeds in dim environments while creating noticeable subject separation when shooting close to subjects.

• Optical Construction: 14 elements in 11 groups, featuring 3 aspherical elements, 4 ED glass elements, and 3 HRI elements.
• Close-Up Capability: Features a minimum focus distance of 0.26 meters (10.2 inches) with a maximum magnification ratio of 0.15x (1:6.67).
• Dimensions & Weight: Measures 76 × 106.6 mm, weighs approximately 550g, and accepts standard 62mm front filters.

Hardware Considerations & Practical Notes

Before selecting your mount, keep these technical factors in mind:

• Initial Mount Staggering: Sony E and Leica L mounts ship first in late 2026; Nikon Z and Fujifilm X versions are scheduled to launch in Q1 2027.
• Physical Weight Balance: At ~540g to 550g each, both lenses are built solidly with metal barrels, which may feel front-heavy on compact, grip-less mirrorless bodies.

Price and Availability

The Sirui Aurora 15mm f/1.6 is priced at $599 USD, while the Sirui Aurora 24mm f/1.4 carries an MSRP of $499 USD. Pre-orders are open immediately for Sony E-mount and Leica L-mount variants through the official Sirui online store and authorized distributors such as B&H Photo, with official retail shipments commencing on November 16, 2026. Nikon Z-mount and Fujifilm X-mount versions will arrive in the first quarter of 2027.

Final Summary

The addition of the Aurora 15mm f/1.6 and 24mm f/1.4 turns Sirui’s full-frame autofocus lineup into a robust four-lens set alongside the 35mm f/1.4 and 85mm f/1.4. By combining low distortion optical designs, weather sealing, screw-in filter threads, and competitive pricing ($499–$599), Sirui delivers immense value for wide-angle shooters.
