Our verdict
For $449, the Aurora 85mm gives portrait shooters f/1.4 depth of field, a sharp centre wide open and smooth, round bokeh from 15 aperture blades. Autofocus is its weakest point: fine for portraits, slower than Sony’s GM II or Sigma’s Art lenses, and one Fujifilm tester needed a free calibration. If you shoot people rather than sport, it is outstanding value.
What we like
- Full-frame f/1.4 for $449 (list $599)
- Sharp in the centre wide open; peaks at f/2.8–f/4
- 15 aperture blades give round, smooth out-of-focus highlights
- Solid build with a smooth aperture ring and sturdy hood
- Four mounts: Sony E, Nikon Z, L-mount, Fujifilm X
What could be better
- Stepping-motor autofocus is slower than native and Sigma Art lenses
- Corners softer than expected until f/4
- Fujifilm compatibility still maturing; one test copy needed calibration
- Some flare and ghosting into bright light

What is it?
The Aurora is SIRUI’s first full-frame autofocus portrait lens, and it lands in a crowded but expensive category. Native 85mm f/1.4 lenses from Sony, Nikon or Sigma cost two to four times as much. SIRUI asks $449 at the time of writing (list $599), in Sony E, Nikon Z, L-mount and Fujifilm X versions.
Technical overview
- 14 elements in 9 groups, 15 aperture blades.
- f/1.4 to f/16 with an aperture ring.
- Minimum focus 0.85 m (0.12×), 67 mm filters.
- About 550 g, 80.3 × 101.7 mm.
- Stepping-motor (STM) autofocus.
Image quality
Reviewers broadly agree it is sharp for the money:
- CineD, on a Sony a1 II, found it sharp even at f/1.4.
- Fstoppers, summarising Dylan Goldby’s test on Fujifilm, called the wide-open centre impressive, with sharpness rising by f/2 and peaking at f/2.8–f/4. Corners were softer than expected until f/4.
- PetaPixel rated its sharpness highly, comparing its look to Sony’s G Master lenses at a fraction of the price.
Chromatic aberration is present but normal for an f/1.4 lens. Flare and ghosting show up in extreme backlight. The 15-blade aperture keeps highlights round, and testers describe the rendering as less clinical than modern native lenses, with an older, more characterful look.
Autofocus
This is the honest trade-off:
- PetaPixel describes the motor as a more pedestrian STM design.
- Fstoppers says AF is generally fast and accurate, but does not match native lenses or the Sigma Art series.
- Dustin Abbott notes Sony’s 85mm GM II, with two XD linear motors, is much faster.
- On Fujifilm, the test copy had an initial accuracy problem. SIRUI calibrated it for free, after which it focused quickly and reliably. AF slowed when stopped down, and disabling face detection helped. The X-T5 and X-H2S were the most reliable bodies.
For posed portraits and weddings, it is fine. For running kids or sport, a native lens is safer.
Aurora 85mm vs the rivals
- vs Sony FE 85mm F1.4 GM II: much faster autofocus and better corners, at several times the price.
- vs Sigma 85mm F1.4 DG DN Art: faster, more consistent AF; also much more expensive.
- vs SIRUI Sniper 56mm F1.2: the APS-C option, cheaper again, but softer wide open. See our Sniper review.
Price and value
At $449, the Aurora is one of the cheapest ways to get full-frame f/1.4 portraits with autofocus. Update the firmware before your first shoot.
Final thoughts
If you photograph people who stand still long enough to smile, the Aurora 85mm delivers images that look far more expensive than they were. Accept slower AF, and it is a bargain.
