Sigma 105mm T1.5 FF Classic Art Prime

Ultra Cinematic Tele Lens

The Sigma 105mm T1.5 FF Classic Art Prime is an ultra telephoto full-frame cinema lens designed for extreme subject isolation, controlled compression, and highly expressive cinematic framing. It is a key tool for narrative filmmaking, commercial productions, and portrait cinematography requiring maximum separation between subject and background.

The 105mm focal length delivers strong compression, creating a visually intimate yet spatially compressed perspective that enhances emotional focus and subject prominence.

The Classic Art optical tuning introduces reduced contrast, enhanced flare behavior, and subtle halation, producing a more atmospheric and analog-inspired cinematic image response.

The T1.5 aperture allows extremely shallow depth of field and exceptional low-light performance, making it ideal for stylized close-ups, controlled studio lighting, and night cinematography.

Optically, the lens delivers high resolution across the full frame, with smooth tonal rendering and consistent color reproduction across the Sigma Classic Art Prime series. Focus breathing is minimized for stable cinematic operation.

Mechanically, it follows full cine standards with 0.8 MOD gearing, long precision focus throw, and robust metal construction built for demanding professional workflows.
