On 25 September 2025, Sirui added a new gem to its growing Aurora lineup: the Aurora 35mm f/1.4 full-frame autofocus lens. This is the second lens in the Aurora series (after the 85mm f/1.4) and marks a strong step toward a versatile prime toolkit for photographers and videographers seeking a balance of portability, speed, and quality.
Main Specs & Features
- Focal Length & Format: 35 mm, full-frame coverage. Works with major mirrorless mounts: Sony E, Nikon Z, Leica L, Fujifilm X.
- Maximum Aperture: f/1.4 — great for low-light, shallow depth-of-field shots, and creative bokeh.
- Optical Construction: 16 optical elements arranged in 11 groups, including specialty elements — SED (ultra-low dispersion), ED, HRI, and several aspherical lenses — designed to reduce aberrations, control chromatic aberration and minimize flare while delivering sharpness and contrast.
- Aperture Blades: 13-blade circular diaphragm, for smooth, pleasing bokeh and gradient transitions.
- Minimum Focus Distance & Magnification: 0.35 m (≈ 1.15 ft), with maximum magnification ratio of ~0.14× — enabling relatively close-up shots with natural perspective.
- Angle of View: ~65.7°, providing a classic “normal-to-wide” field of view useful for a wide variety of genres: street, environmental portraits, travel, documentary, landscape.
- Filter Thread & Build: 62 mm filter thread; robust all-metal construction; dust- and moisture-resistant design with fluorine-coated front element to resist fingerprints, oil and dirt.
- Size & Weight: Around 490 g (mount-dependent), with a compact profile — considerably lighter and more portable than many competing 35 mm f/1.4 lenses.
- Autofocus: STM (stepping motor) autofocus, with support for eye/face detection (depending on camera body), suitable for both stills and video.
- Mount Compatibility: Available for Sony E, Nikon Z, Leica L (thanks to Sirui joining the L-Mount Alliance), and Fujifilm X — giving wide flexibility across major mirrorless systems.
Who the Aurora 35mm f/1.4 Is Think For
This lens seems ideal for photographers and creators who value:
- Versatility: 35 mm on full frame (or ~50-52 mm equivalent on APS-C) — a classic “walkaround” focal length that works for street, documentary, travel, environmental portraiture, and event work.
- Low-light shooting & shallow depth-of-field: The generous f/1.4 aperture makes it suitable for night scenes, indoor available-light situations, or creative bokeh work.
- Portability & travel-friendliness: Thanks to its relatively light build and compact size, it’s a strong candidate for photographers on the move, vloggers, or hybrid shooters who don’t want bulky gear.
- Cross-system flexibility: With multiple mount options (E, Z, L, X), it can serve users across Sony, Nikon, Leica, Fujifilm — a plus for those switching systems or owning multiple cameras.
- Value-conscious creatives: As part of Sirui’s drive to deliver capable optics at more approachable price points, the Aurora 35 mm f/1.4 appears to offer a compelling balance of speed, build, and flexibility — especially when compared to many premium-brand 35 mm primes.
