Sigma 50mm f1.4 Art Nikon F 508734787 - 1773997

This Sigma 50mm f1.4 DG Art Lens for Nikon F, #50873478, is in great condition with minor handling wear. I rate it cosmetically a (9). The focus ring is a bit stiff and makes some slight noise. The autofocus and aperture function properly, and the glass is clean and clear with no haze, marks, or fungus. There are a few faint specks of dust inside, but they do not affect image quality. This lens includes front & rear caps.

What our Experts Think

• Iconic “fast normal” prime for pro Nikon shooters
  The Sigma 50mm f/1.4 DG HSM Art (Nikon F) delivers a classic 50 mm field of view with a wide f/1.4 aperture — perfect for portraits, street scenes, environmental shots, and low‑light work thanks to its bright, versatile rendering.
• Outstanding optical resolution & contrast
  With a sophisticated optical formula of 13 elements in 8 groups, including SLD and aspherical glass, this Art‑series lens minimizes chromatic aberrations and delivers crisp, detailed images with rich contrast and minimal distortion.
• Creamy bokeh and depth‑of‑field control
  The f/1.4 maximum aperture and 9‑blade rounded diaphragm produce smooth background separation and beautiful out‑of‑focus qualities — ideal for portraiture and subject isolation.
• Reliable AF with full‑time manual focus
  The ring‑type ultrasonic motor (HSM) provides fast, quiet autofocus with full‑time manual override, helping ensure focus precision in stills and video — though some users may fine‑tune with calibration tools on older DSLRs.
• Durable build & professional handling
  Well‑constructed with metal components and a 77 mm filter thread, this lens feels solid on Nikon F bodies and includes a hood and caps — though it’s heavier than typical nifty‑fifty‑style primes due to its advanced optics.
• Great all‑around performer
  Tested by reviewers and users alike, it’s widely regarded as one of the sharper and more capable 50 mm f/1.4 primes, often competing well above its price point and delivering consistent results across genres.

Maintenance Tips

• Clean lens elements carefully: Use a microfiber cloth and lens-safe cleaning solution to remove dust, fingerprints, and smudges without damaging the coatings.
• Use lens caps and hood: Always cover the front and rear elements during storage or transport to prevent scratches and debris.
• Protect from dust and moisture: Store in a padded, dry case; avoid rain, humidity, or sandy environments.
• Inspect and clean lens mount: Keep metal contacts free of debris for stable electronic communication with the camera.
• Handle with care: Avoid impacts and excessive force on the focus ring or barrel to prevent misalignment of optical elements.
• Check autofocus and aperture function: Periodically test to ensure smooth focus and accurate aperture performance.
• Consider a protective filter: Optional UV or clear filter can safeguard the front element without affecting image quality.
• Schedule professional servicing: Annual inspection by an authorized service center helps maintain long-term optical and mechanical performance.
