Sirui has added two fast wide-angle primes to its Aurora line: the sirui aurora 15mm lens, a 15mm f/1.6, and a 24mm f/1.4. Both are autofocus lenses for full-frame mirrorless cameras, aimed at stills shooters and video creators.
The 15mm f/1.6 is the wider of the pair. Sirui says it keeps distortion low despite an ultra-wide field of view. The company recommends it for architecture, travel, vlogging, and night shooting. The f/1.6 maximum aperture also gives photographers more room to balance shutter speed and ISO.
Fast glass works best with steady support, so Sirui’s own gear is worth a look too. Sirui’s BH-60 dual-function tripod head covers both stills and video work.
Distortion is the main design target for the sirui aurora 15mm lens. Ultra-wide lenses, and any wide-angle lens, often bend straight lines, especially near the edges of the frame. Sirui says it reduced that effect, which matters most for interiors and video work.
Sirui puts it this way: the lens is “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 sirui aurora 15mm lens
The 15mm’s optical design uses 17 elements in 12 groups. Three are aspherical, three are ED (extra-low dispersion) glass, and four are HRI (high refractive index) elements. An 11-blade diaphragm sets the aperture. A dedicated control ring can be de-clicked, which allows smoother changes while recording.
Unlike some ultra-wide designs, the sirui aurora 15mm lens takes standard 77mm front filters. It is 106.4 millimeters, or just under 4.2 inches, long. The lens weighs 540 grams, or 19 ounces. Its closest focusing distance is 0.3 meters (0.98 feet), which produces a maximum magnification of 1:12.5.
The 24mm f/1.4 covers the same work as the 15mm and adds environmental portraits. It also suits scenes where a more natural perspective matters. Sirui positions it alongside the existing Aurora 35mm f/1.4, offering a similar handling experience with a wider view.
Sirui describes the 24mm this way: “Its 24mm focal length provides a wider view than a traditional 35mm lens without the exaggerated perspective often associated with ultra-wide lenses.”
For video, the 24mm offers a de-clickable aperture ring, stepless aperture control, and reduced focus breathing. Its STM autofocus system promises quick, quiet focusing. It also supports eye-tracking and subject-detection modes.
At 106.6 millimeters (4.2 inches) long and 550 grams (19.4 ounces), the 24mm runs slightly longer and heavier than its wider sibling. It takes 62mm front filters.
Fourteen elements sit in 11 groups. Three of them are aspherical, four are extra-low dispersion, and three are high refractive index. The diaphragm has 11 blades, the same count as the 15mm.
Availability and pricing
Both lenses have weather-resistant construction. Sirui lists mounts for Sony E, Nikon Z, Leica L, and Fujifilm X. The Sony E and Leica L versions are available now. The Nikon Z and Fujifilm X versions are slated for Q1 2027.
Fujifilm X shooters waiting on the Q1 2027 release may also want to compare recent launches. Laowa’s first autofocus lens for Fujifilm X-mount shows what the competition offers for that mount today.
Sirui’s 24mm f/1.4 sits at the low end of a crowded field. Sony’s FE 24mm f/1.4 GM costs $1,498, and Sigma’s 24mm f/1.4 DG DN Art is $879. Meike’s AF 24mm f/1.4, a Chinese-made competitor, lists at $589. At $499, Sirui is the least expensive of the four.
No other lens matches the focal length and aperture combination of the sirui aurora 15mm lens. The nearest alternatives are 14mm lenses: Sony’s FE 14mm f/1.8 GM at $1,598 and Sigma’s 14mm f/1.4 DG Art at $1,839. Closer in price are Sony’s FE 16mm f/1.8 G at $898 and Viltrox’s AF 16mm f/1.8 at $580. The sirui aurora 15mm lens costs $599.
For buyers who want fast wide primes without flagship prices, the Aurora pair raises the pressure on the category. The distortion claims are the figures to verify. Lab tests and side-by-side field reviews will show whether they hold.
