Sirui’s Affordable Aurora Series Goes Wider With 15mm f/1.6 and 24mm f/1.4 Primes

Sirui has announced the Aurora 15mm f/1.6 and 24mm f/1.4 wide-angle lenses for full-frame mirrorless cameras.

These fast, autofocus-equipped wide-angle lenses are designed for both photographers and videographers, promising reliable autofocus and high-end image quality across a wide range of scenarios.

Despite its ultra-wide field of view, the 15 mm f/1.6 lens promises very low distortion. Sirui says it is well-suited to architectural photography, travel, vlogging, and night shooting. The fast f/1.6 aperture should also enable more creative options for shutter speed and ISO.

The company says that distortion control has been a key focus for the lens’s design. Ultra-wide lenses can often make straight lines appear curved, especially near the edges of the frame. Sirui promises it has minimized these issues with its new lens, making it “particularly valuable for architecture and interior photography, as well as video production, where reducing distortion can also mean less correction and cropping in post-production.”

Inside, the 15mm f/1.6 lens features 17 elements arranged in a dozen groups. It includes three aspherical elements, three ED elements, and four HRI elements. The lens includes an 11-bladed aperture diaphragm, and its dedicated aperture control ring can be de-clicked for smoother operation during video recording.

Further, unlike some ultra-wide lenses, the Sirui Aurora 15mm f/1.6 accepts standard front 77mm filters. The lens is 106.4 millimeters (just under 4.2 inches) long and weighs 540 grams (19 ounces). It can focus as close as 0.3 meters (0.98 feet), for a max magnification ratio of 1:12.5.

For those needing a bit more reach, the Aurora 24mm f/1.4 lens should work well for many of the same applications as the 15mm f/1.6, plus environmental portraits and scenes with more natural perspective. It offers a similar experience to the existing Aurora 35mm f/1.4, albeit with a wider field of view.

“Its 24mm focal length provides a wider view than a traditional 35mm lens without the exaggerated perspective often associated with ultra-wide lenses,” Sirui says of its new lens.

The 24mm f/1.4 includes some features tailor-made for video applications, including a de-clickable aperture ring, stepless aperture control, and minimized focus breathing. Like the 15mm f/1.6 lens, the 24mm f/1.4 prime has an STM autofocus system that promises quick, quiet focusing, plus support for eye-tracking and subject-detection AF modes.

The Aurora 24mm f/1.4 lens is 106.6 millimeters (4.2 inches) long and weighs 550 grams (19.4 ounces). It accepts 62mm front filters.

The 24mm f/1.4 includes 14 elements in 11 groups. There are three aspherical elements, four ED elements, and three HRI elements. Like the ultra-wide prime, the 24mm f/1.4 also sports an 11-bladed aperture.

Pricing and Availability

Both new Sirui Aurora lenses feature a weather-resistant design and are available for Sony E, Nikon Z, Leica L, and Fujifilm X. However, only the E- and L-Mount versions are available now, with the Z- and X-mount lenses slated to arrive in Q1 2027.

Many 24mm f/1.4 lenses are on the market, including premium options from Sony (FE 24mm f/1.4 GM, $1,498) and Sigma (24mm f/1.4 DG DN Art, $879). Another Chinese-made competitor is the $589 Meike AF 24mm f/1.4. Sirui is the cheapest of the bunch, priced at just $499.

As for the new Sirui Aurora 15mm f/1.6, it is the only lens with that exact focal length and aperture combination on the market, but there are 14mm lenses like the Sony FE 14mm f/1.8 GM ($1,598) and Sigma 14mm f/1.4 DG Art ($1,839) to consider. There’s also the Sony FE 16mm f/1.8 G ($898) and Viltrox AF 16mm f/1.8 ($580), which are much closer in price to Sirui’s new option. The Sirui Aurora 15mm f/1.6 is $599.
