Sirui’s Aurora 35mm f/1.4 Lens Announced

Sirui has officially announced the new Aurora 35mm f/1.4, making it the second lens in a series of lightweight, fast primes that kicked off with the Aurora 85mm f/1.4 earlier this year. The lens was on display at IBC Amsterdam a few days ago, giving us an early look before its official release later this month. Sirui plans to round out the Aurora series with five focal lengths in total, aiming to offer creatives a compact and affordable set of primes.

The 35mm f/1.4 is a full-frame lens that will ship in Sony E, Nikon Z, Leica L, and Fujifilm X mounts. Despite its all-metal build, it comes in at roughly 490 grams depending on the mount, which is light compared to many modern full-frame primes. The lens uses a 62mm filter thread and packs a fairly complex optical design: one SED ultra-low dispersion element, two ED elements, one high refractive index element, and three aspherical elements, all treated with nano multi-coating to help reduce reflections and improve contrast. Autofocus is handled by a stepping motor, with support for eye-tracking across compatible camera bodies.

At IBC, early hands-on impressions noted how surprisingly light the 35mm felt, especially against the backdrop of today’s often hefty high-end glass. Performance expectations are more modest than flagship lenses from Sony or Nikon, but Sirui seems to be betting on portability and price to win attention. The Aurora 35mm f/1.4 is expected to launch on September 29th for $549.
