Product Information

Full details

The Sigma 14-24mm F2.8 DG DN Art lens is designed for full-frame mirrorless camera users, especially those engaged in astrophotography and seeking high resolution in wide-angle shots. Its key benefit is exceptional clarity and light-gathering capability for low-light conditions. A potential caveat is its specialized nature, which might be overkill for general-purpose wide-angle needs. Key features include its large F2.8 aperture, advanced optical elements for aberration control, robust build, and quiet autofocus for video.

FAQs

What is the primary use case for this lens?

This lens is optimized for astrophotography and general wide-angle photography where high resolution and low-light performance are critical. Its F2.8 aperture and advanced optics make it ideal for capturing the night sky and challenging lighting conditions.

Is this lens suitable for video recording?

Yes, the quiet stepping motor provides smooth and silent autofocus, which is highly beneficial for video recording, minimizing distracting operational noise.

What does 'DG DN' mean in the lens name?

'DG' indicates the lens is designed for full-frame digital cameras, while 'DN' signifies it's optimized for mirrorless cameras with short flange focal distances.

How does the Nano Porous Coating (NPC) help?

NPC, combined with the Super Multi-Layer Coating, significantly reduces internal reflections and enhances light transmission, making the lens resistant to strong incident light and minimizing flare and ghosting.

Can I use this lens on APS-C mirrorless cameras?

While it will physically mount and function on APS-C mirrorless cameras (likely with an adapter if not L-mount), it will operate as a cropped image circle. The 'DG' designation implies it's designed for full-frame sensors, so using it on APS-C might not leverage its full potential or intended field of view.

What is the closest focusing distance?

The closest focusing distance is 0.28 meters (28 cm).

What is the maximum aperture?

The maximum aperture is F2.8.

Is the lens weather-sealed?

Yes, the lens features a dust- and splash-proof structure, along with a water- and oil-repellent coating on the front element, providing reliable performance in various environmental conditions.

Troubleshooting

Autofocus is slow or hunting.

Ensure your camera's firmware is up-to-date and compatible with the lens. Clean the lens contacts and camera mount contacts. Try using manual focus or switching AF modes.

Image quality is not as expected (softness, aberrations).

Confirm the lens is correctly mounted. Ensure you are shooting at appropriate apertures; F2.8 is wide, and stopping down to F4 or F5.6 can improve sharpness. Check for lens element smudges.

Lens hood is difficult to attach/detach.

Ensure the hood is aligned correctly with the bayonet mount. Do not force it; apply gentle, consistent pressure.

Lens does not communicate with the camera.

Clean the electronic contacts on both the lens and camera body. Re-mount the lens. Check camera settings for correct lens communication.

Pros and Cons

Pros

  • Outstanding resolution, particularly for astrophotography.
  • Excellent control of chromatic aberration and coma flare.
  • Effective resistance to backlight, flares, and ghosting.
  • Fast, quiet, and smooth autofocus suitable for stills and video.
  • Robust, weather-sealed construction for durability.
  • Wide F2.8 aperture ideal for low-light conditions.

Cons

  • Can be large and heavy for some mirrorless systems.
  • Ultra-wide focal range may not be suitable for all photographic styles.
  • Front element may be susceptible to smudges with the oil-repellent coating.
  • AF performance may vary slightly between different camera bodies.
  • No built-in image stabilization.

Setup, Compatibility & Care

This lens is designed for full-frame mirrorless cameras with an L-Mount interface. Ensure your camera body is compatible before purchase.

Setup:

  1. Align the lens mounting index with the corresponding index on your camera body.
  2. Insert the lens and rotate it clockwise until it clicks into place.
  3. To remove, press the lens release button on the camera and rotate the lens counter-clockwise.

Compatibility: Primarily designed for cameras with the L-Mount. Please refer to Sigma's official compatibility charts for specific camera models.

Care:

  • Cleaning: Use a soft, lint-free microfiber cloth to clean the lens elements. For stubborn smudges, use a lens cleaning solution sparingly on the cloth. Avoid touching the lens elements with your fingers.
  • Coating: The front element has a water- and oil-repellent coating. For general cleaning, a dry microfiber cloth is often sufficient.
  • Storage: Store the lens in its original pouch or a padded camera bag to protect it from dust, moisture, and impact. Avoid extreme temperatures.
  • Weather Sealing: While dust and splash-proof, avoid prolonged exposure to heavy rain or harsh weather. If exposed, gently wipe dry immediately.
