Key facts
All specs below are from Sirui's product pages.
| Aurora 15mm f/1.6 | Aurora 24mm f/1.4 | |
|---|---|---|
| Optics | 17 elements in 12 groups | 14 elements in 11 groups (3 aspherical, 4 ED, 3 HRI) |
| Aperture blades | 11 | 11 |
| Minimum focus | 0.3m | 0.26m |

| Length (E / L) | 106.4mm / 104.4mm | 106.6mm / 104.6mm |
Both use an STM focus motor and a 360° focus ring. The 15mm page lists a 109.3° diagonal angle of view. The 24mm page lists 82.93°.
Where they sit in the Aurora line
The 15mm and 24mm join the existing Aurora 35mm f/1.4 at $549 and 85mm f/1.4. Sirui's store showed the 85mm at $404.10, marked 33% off a $599 list price, when we read it.
The new 24mm is the cheapest f/1.4 lens in the line at $499, $50 below the 35mm. The 15mm matches the 85mm's list price and is the priciest of the four at current store prices.
How the prices compare
At 24mm, the nearest f/1.4 lenses for Sony E mount cost more, per B&H on Nov. 9:
- Sigma 24mm f/1.4 DG DN Art: $879, in stock
- Sony FE 24mm f/1.4 GM: $1,498, down from $1,598 with a $100 holiday saving, in stock
At the wide end, the closest autofocus rival we checked is the Viltrox AF 16mm f/1.8 FE at $580, in stock at B&H. It is slightly narrower and a third of a stop slower than the Aurora 15mm f/1.6, which costs $19 more.
Why it matters
The 24mm f/1.4 is the story. At $499 it undercuts Sigma's Art lens by $380 and Sony's G Master by nearly $1,000. We have not tested the Aurora, so how much of that gap shows up in sharpness, autofocus or build is unknown.
The cost of waiting is the lack of a date. Both lenses are pre-orders, Sirui gives no ship date (B&H estimates Nov. 16) and there is no independent testing yet. Sigma, Sony and Viltrox lenses are in stock now.

What we checked
We read Sirui's four Aurora product pages in its U.S. dollar view, B&H's listings for the three rival lenses and B&H's pages for the Aurora 15mm (Sony E) and 24mm (Sony E and L) on Nov. 9, 2026, between about 10:55 and 11:05 a.m. ET. Sony Alpha Rumors first flagged the launch on Nov. 9. We have not tested the lenses. Sirui's pages did not state a ship date. B&H links are affiliate links.
