Sigma 85mm T1.5 FF Classic Art Prime

The Sigma 85mm T1.5 FF Classic Art Prime is a long telephoto full-frame cinema lens designed for expressive portraiture, emotional storytelling, and strong subject isolation with a distinctly organic rendering character. It is one of the most important focal lengths in the Classic Art Prime lineup for cinematic close-ups and dialogue-driven framing.

The 85mm field of view delivers strong natural compression, enhancing facial structure while separating subjects clearly from the background. This makes it ideal for interviews, dramatic close-ups, and controlled narrative cinematography.

The Classic Art optical tuning introduces reduced contrast, enhanced flare behavior, and subtle halation, producing a more atmospheric and emotionally rich image response compared to modern high-contrast cine optics.

The T1.5 aperture enables extremely shallow depth of field and excellent low-light performance, allowing cinematographers to isolate subjects even in challenging lighting conditions while maintaining a filmic aesthetic.

Optically, the lens delivers high resolution, smooth tonal transitions, and consistent color reproduction across the Sigma Classic Art Prime series. Focus breathing is carefully controlled for stable framing during focus pulls.

Mechanically, it follows full cine standards with 0.8 MOD gearing, long focus throw for precision operation, and robust all-metal construction designed for professional production environments.
