Sirui Adds Two Wide Aurora Autofocus Primes: 15mm f/1.6 for $599, 24mm f/1.4 for $499

Sirui announced two new full-frame autofocus lenses for its Aurora series on November 9: a 15mm f/1.6 for $599 and a 24mm f/1.4 for $499.

Both ship first in Sony E and Leica L mounts, with Nikon Z and Fujifilm X versions due in Q1 2027, according to Newsshooter.

They join the Aurora 35mm f/1.4 and 85mm f/1.4.

Aurora 15mm f/1.6

The 15mm uses 17 elements in 12 groups, including three aspherical, three ED and three HRI elements. It has 11 aperture blades and a 109.3° diagonal view on full frame.

Minimum focus is 0.3 meters, and the lens takes 77mm filters. Weight is 542 g in E mount and 550 g in L mount, per Sirui’s product page. Sirui says distortion is held to about 1.4%.

Aurora 24mm f/1.4

The 24mm uses 14 elements in 11 groups, with three aspherical, four ED and three HRI elements. It also has 11 blades, and a 82.9° diagonal view.

Minimum focus is 0.26 meters, and the lens takes 62mm filters. It weighs 550 g in E mount and 560 g in L mount, per Sirui’s product page. Sirui lists low focus breathing among its features.

Shared Controls and Build

Both lenses use an STM focus motor and work with compatible cameras’ eye detection and subject tracking. The aperture ring switches between clicked and de-clicked, and an iris lock holds it in the A or manual position.

Each has an AF/MF switch, a customizable Fn button, a USB-C port for firmware updates and an all-metal body. Sirui rates them as dust, stain and splash resistant. Its compatibility lists mark a few older Sony bodies, such as the a6000, as partially compatible in video mode.

Competitive Context

Sony’s FE 24mm f/1.4 GM launched at $1,398, per DIY Photography. On the ultra-wide side, the Sony FE 14mm f/1.8 GM and the Sigma 14mm f/1.4 DG DN Art were both listed at about $1,598 to $1,599, per Brian Smith. Those are launch-era prices, so check current ones.

Viltrox’s AF 16mm f/1.8 for Sony E went up for pre-order at $549, per Digital Camera World. For more third-party autofocus primes, see Viltrox AF 75mm F1.8 & 90mm F2.2 EVO Lenses Launch and 7Artisans Teases Ultra-Wide AF Prime for Full Frame.

The Signal in the Noise

The pitch is price. A 24mm f/1.4 at $499 and a 15mm f/1.6 at $599 undercut the name-brand fast wides by wide margins, and both sit near 550 g.

Distortion and focus breathing figures are Sirui’s own. Autofocus tracking, corner sharpness and video behavior need independent tests, and I found none yet.

The 77mm and 62mm filter threads allow ND filters on both lenses, which suits run-and-gun video. Nikon Z and Fujifilm X shooters wait until Q1 2027.

Would you trade a name-brand label for a $499 autofocus 24mm f/1.4, or does autofocus reliability in video keep you on Sony and Sigma glass?
