Compare the Sigma 14-24mm f/2.8 DG DN Art zoom and the Sigma 14mm f/1.8 DG HSM Art prime for Sony E-mount. See which ultra-wide lens fits your landscape, astrophotography, or travel needs.
Quick answer
Choose the Sigma 14-24mm f/2.8 DG DN Art for flexible composition in landscapes and travel, or the Sigma 14mm f/1.8 DG HSM Art for superior low-light performance in astrophotography.
Key differences at a glance
The Sigma 14-24mm f/2.8 DG DN Art is a zoom lens designed for the Sony E-mount, offering a versatile focal range from ultra-wide to wide. It features a stepping motor for fast autofocus and a weather-sealed build. The Sigma 14mm f/1.8 DG HSM Art is a prime lens with an exceptionally fast f/1.8 aperture, the world's first full-frame ultra-wide prime at that speed, making it ideal for capturing stars and low-light scenes.
Your choice depends on whether you value zoom flexibility or maximum light gathering. The zoom covers 14-24mm, letting you adjust framing without changing lenses, while the prime's wider aperture lets in over twice as much light, critical for astrophotography.
Trade-offs to consider
- Versatility vs specialization: The 14-24mm zoom covers a range of ultra-wide perspectives, from dramatic close-ups to sweeping vistas, all with one lens. The 14mm prime locks you into a single, very wide angle but delivers the fastest aperture in its class.
- Autofocus speed and build: The zoom uses a stepping motor for quick, quiet autofocus, and its weather-sealed body with protective front coating is built for outdoor use. The prime relies on HSM (Hyper Sonic Motor) and lacks the same level of weather sealing, though it remains robust for most shooting.
- Aperture and low-light performance: The 14mm f/1.8 gathers about 2.3 times more light than the 14-24mm at f/2.8, significantly reducing exposure times for astrophotography. The zoom's f/2.8 is still fast enough for most landscapes but will require longer shutter speeds or higher ISO in very dark conditions. If astrophotography is a priority, the prime's f/1.8 is a distinct advantage you cannot get from the zoom.
Product facts
- Sigma 14-24mm f/2.8 DG DN Art Lens for Sony-E Mount: The Sigma 14-24mm f/2.8 DG DN Art has a constant f/2.8 aperture, a stepping motor for high-speed AF, and a weather-sealed design with a built-in lens hood. You get a durable, fast-focusing zoom that handles changing conditions and lets you compose quickly without swapping lenses.

Sigma 14-24mm f/2.8 DG DN Art Lens for Sony-E Mount - Sigma 14mm f/1.8 DG HSM Art Lens for Sony E-Mount: The Sigma 14mm f/1.8 DG HSM Art is the world's first full-frame ultra-wide prime with an f/1.8 aperture, featuring 16 elements in 11 groups and a minimum focus of 27 cm. That extra stop of light (compared to f/2.8) makes a real difference for astrophotography and interior shots where every photon counts.

Which lens fits you?
Best for
- Landscape and travel photographers who want one lens for multiple ultra-wide angles and need fast, quiet autofocus.
- Astrophotographers who need the widest possible aperture to capture stars and the Milky Way with minimal noise.
Not ideal for
- Shooters who need a single ultra-wide prime for consistent framing and maximum light gathering should skip the zoom.
- Those who want zoom flexibility and weather sealing for outdoor adventures should skip the prime.
