Sigma 28mm T1.5 FF Classic Art Prime

Versatile Cinematic Character Wide Lens

The Sigma 28mm T1.5 FF Classic Art Prime is a versatile wide-angle full-frame cinema lens designed for immersive storytelling with a strong organic character profile. It is one of the most flexible focal lengths in the Classic Art lineup.

The optical tuning introduces reduced contrast, enhanced flare behavior, and subtle halation, producing a distinctly cinematic and emotionally expressive image.

The T1.5 aperture enables strong low-light performance and shallow depth of field even in wide-angle compositions, allowing controlled subject separation.

Optically, the lens maintains high resolution while emphasizing character over clinical neutrality. Focus breathing is minimized for stable cinematic operation.

Mechanically, it follows full cine standards with 0.8 MOD gearing, metal construction, and 95mm front diameter for consistent rig integration.
