Sigma 15mm f1.4 DG DN - Sony E - 1593375

In developing a fisheye lens featuring an ultra-wide-angle and powerful fisheye distortion, SIGMA has achieved a completely new level of artistic potential, combining the world's first F1.4 aperture for consumer use with outstanding resolving power across the entire image. In terms of optical performance, the SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE | Art has achieved excellent point image reproducibility and high resolution by correcting various aberrations, especially sagittal coma flare. The lens is capable of handling starscape photography, which demands particularly high-quality performance, even when wide-open. Unlike conventional fisheyes, the SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE | Art is exceptionally sharp across its entire 180° angle-of-view and offers an ultra-fast F1.4 aperture, making it perfect for a wide range of applications including astrophotography, landscapes and architecture. The expressive power of this all-new full-frame mirrorless lens opens a wealth of creative possibilities in wide-angle photography.

What our Experts Think

• Ultra-fast fisheye = unmatched creative potential
  The Sigma 15mm f/1.4 DG DN (Sony E) is the world’s first full-frame diagonal fisheye with f/1.4, delivering a dramatic 180° field of view with exceptional brightness—ideal for astro, landscapes, and creative work.
• Outstanding low-light & astrophotography performance
  The wide f/1.4 aperture captures more light and minimizes noise, while advanced optics reduce coma and preserve sharp stars across the frame.
• Sharpness across the entire frame
  Complex optical design (21 elements, including FLD/SLD and aspherical elements) delivers high resolution even at ultra-wide angles—rare for fisheye lenses.
• Pro-level build & features
  Weather-sealed construction, built-in hood, tripod collar, rear filter holder, and manual focus lock make it highly capable for demanding outdoor and long-exposure work.
• Creative versatility beyond landscapes
  Minimum focus distance (~15 inches) allows dramatic close-ups with exaggerated perspective—great for action, interiors, and unique storytelling shots

Maintenance Tips

• Clean front element carefully: Use a blower + microfiber cloth—bulbous fisheye glass is highly exposed and prone to scratches.
• Use rear filter holder properly: Only insert compatible gel filters to avoid internal damage.
• Keep lens cap on when not in use: Built-in hood + cap helps protect the large curved front element.
• Check weather sealing: Wipe moisture/dust after use—lens is dust & splash resistant but not waterproof.
• Avoid touching glass surface: Oils are more visible on ultra-wide fisheye optics and affect image quality.
• Store in padded case: At ~1.36 kg, proper storage prevents mount stress and optical misalignment.
• Inspect mount & contacts: Keep Sony E contacts clean for reliable autofocus and aperture control.
• Use tripod collar when needed: Reduces strain during long shoots (astro/landscape).
• Update camera firmware: Ensures optimal AF performance and compatibility with advanced features
