Sirui Expands Aurora Series With Two New Wide-Angle Prime Lenses

Sirui continues to expand its autofocus lens lineup, introducing two new wide-angle primes for full-frame cameras. The new Aurora 15mm F1.6 and 24mm F1.4 join the company’s growing Aurora series, bringing fast apertures, autofocus, and compact designs at relatively affordable prices.

The announcement follows a busy couple of weeks for Sirui, which recently introduced the first two models in its Swift series.

Sirui Aurora 15mm F1.6 Promises Low Distortion

The Aurora 15mm F1.6 is an ultra-wide prime designed for landscapes, astrophotography, architecture, and interior photography. It offers a 109.3-degree angle of view on full-frame cameras, with Sirui placing particular emphasis on distortion control.

According to the company, the lens produces just 1.4% distortion, helping keep straight lines from appearing curved toward the edges of the frame. This could make it particularly useful for architectural and interior photography, where maintaining accurate geometry is important.

The optical construction consists of 17 elements in 12 groups, including three aspherical elements, three extra-low dispersion elements, and three high-refractive-index elements. Sirui says the aspherical elements help reduce the lens’s size while correcting spherical aberrations and distortion. The ED and HRI elements are designed to minimize chromatic aberrations and color fringing.

The lens also uses an 11-bladed aperture diaphragm, which Sirui says produces more natural-looking bokeh.

Autofocus is handled by a stepping motor designed to deliver fast, accurate, and quiet focusing. The lens also promises minimal focus breathing for video recording and supports subject detection and tracking with compatible cameras. Its minimum focusing distance is 0.3 meters.

Despite its ultra-wide field of view, the Aurora 15mm F1.6 remains relatively compact. It weighs 550g and measures 106.4mm in length.

The lens features an all-metal construction with dust, stain, and splash resistance. Its controls include an Iris Lock Switch, customizable Fn button, AF/MF switch, and an aperture click switch.

Sirui Aurora 24mm F1.4 Offers a Wider Perspective

The Aurora 24mm F1.4 provides a less extreme wide-angle perspective while offering a faster maximum aperture. Sirui positions it for landscapes, architecture, astrophotography, and travel photography.

Its optical design consists of 14 elements in 11 groups, including three aspherical elements, four ED elements, and three HRI elements. The aspherical elements help reduce weight while correcting spherical aberrations and distortion, while the ED and HRI elements are intended to minimize chromatic aberrations and color fringing.

Sirui says the optical design delivers sharp details at the center of the image while controlling aberrations across the frame.

Like the 15mm, the 24mm uses a stepping motor for autofocus. It supports subject detection and tracking with compatible cameras and offers a minimum focusing distance of 0.26 meters. The maximum magnification ratio is 0.15x, allowing photographers to get relatively close to their subjects.

The Aurora 24mm F1.4 weighs 550g and measures 106.6mm in length. It shares the 15mm’s all-metal construction and dust, splash, and stain-resistant design.

Its controls also include an Iris Lock Switch, customizable Fn button, AF/MF switch, and aperture click switch.

Both lenses include dedicated lens hoods and USB-C ports for future firmware updates.

Pricing and Availability

The Sirui Aurora 15mm F1.6 is priced at $599, while the Aurora 24mm F1.4 costs $499.

Both lenses are now available for Sony E and Leica L mounts through the Sirui online store and B&H Photo. Fujifilm X and Nikon Z versions are expected to arrive in the first quarter of 2027.
