Astrophotography is one of the most exciting and technically demanding areas of photography. It requires a combination of patience, clear skies, and the right gear. Among the top lens manufacturers, SIGMA stands out for offering sharp, fast, and optically advanced lenses that perform exceptionally well under the stars.

This guide explores the best SIGMA lenses for astrophotography, explains what makes them suitable for night sky shooting, and provides useful tips to help you capture stunning images of celestial wonders.

Why SIGMA Lenses Are Perfect for Astrophotography

SIGMA has built a strong reputation for delivering exceptional image quality at competitive prices. Their Art series lenses, in particular, are known for wide apertures, sharp edge-to-edge rendering, and minimal distortion—three things that matter most in low-light photography.

When photographing the night sky, it’s essential that your lens captures as much light as possible while maintaining clarity and minimizing optical flaws like chromatic aberration and coma. This is where SIGMA consistently excels, especially with their prime wide-angle lenses.

Best SIGMA Lenses for Shooting the Night Sky

SIGMA 14mm f/1.8 DG HSM Art

This ultra-wide lens is ideal for shooting vast Milky Way scenes and star trails. With its incredibly fast f/1.8 aperture, it lets in more light than most wide-angle lenses on the market. It offers excellent corner sharpness and low coma—perfect for astrophotography.

SIGMA 20mm f/1.4 DG HSM Art

Offering a balance between width and detail, this lens is perfect for nightscape compositions that include both the sky and the landscape. The f/1.4 aperture provides outstanding light-gathering ability, and the optical quality ensures minimal distortion across the frame.

SIGMA 24mm f/1.4 DG HSM Art

A popular option among night photographers, the 24mm f/1.4 excels in capturing wide scenes with great clarity. It provides a natural field of view and excellent control over coma and vignetting, making it reliable even at its widest aperture.

SIGMA 35mm f/1.4 DG DN Art

Although slightly narrower, the 35mm focal length is great for isolating specific parts of the sky or including more foreground. It’s especially useful for creative compositions involving subjects lit by moonlight or artificial light under a starry backdrop.

SIGMA 105mm f/1.4 DG HSM Art

If you're aiming for close-ups of the moon or detailed sections of the Milky Way, this lens is unmatched. Its telephoto reach and ultra-wide aperture create stunning, high-resolution results with shallow depth-of-field effects, though it’s heavier and requires a sturdy tripod.

What to Look for in an Astrophotography Lens

When choosing a lens for astrophotography, prioritize the following characteristics:

• A wide aperture (f/1.4 to f/2.8) to capture more light in dark conditions

• A wide or ultra-wide focal length to include more of the sky

• Excellent edge-to-edge sharpness to keep stars crisp across the frame

• Minimal coma and chromatic aberration to maintain optical integrity
  
  

SIGMA’s Art series lenses check all these boxes, making them a consistent favorite for astrophotographers worldwide.

Practical Tips for Using SIGMA Lenses at Night

Manual focus is more reliable than autofocus in low light, so use live view on your camera to zoom in on a bright star and focus manually. Always shoot in RAW format to preserve the most data for post-processing. When calculating exposure, the “500 Rule” is a useful starting point—divide 500 by your lens’s focal length to find the maximum number of seconds you can expose before stars begin to trail.

Stability is crucial. Use a strong tripod, a remote shutter release or timer, and avoid touching the camera during exposures. Post-processing tools like Adobe Lightroom or Photoshop can enhance contrast, reduce noise, and bring out more detail from your astrophotography images.

Choosing the Right Camera for Your SIGMA Lens

To get the most out of your SIGMA lens, pair it with a full-frame camera that handles high ISO settings well. SIGMA lenses are available in a variety of mounts including Sony E-mount, Canon RF, Nikon Z, and L-mount systems.
