  • Advanced optical design and outstanding rendering performance

    The optical systems of the Sigma 28-45mm T2 FF incorporate the designs of the highly acclaimed still lenses: the Sigma 28-45mm F1.8 DG DN | Art. Combining the experience gained through years of lens design, the latest development technology, and the advanced manufacturing techniques of Sigma's sole production base, the Aizu factory, these lenses deliver exceptional resolution and beautiful bokeh regardless of focal length or focus position, along with a sharp, clean look with minimal flare and ghosting.

  • Professional-grade mechanical design and operability

    Inheriting the rendering performance and reliability of Sigma’s Art lenses, the AF Cine Line integrates cinema-style mechanics and operability, optimized for professional cinema production. It features a limited-rotation focus ring, industry-standard 0.8M pitch gears, and a clickless aperture ring to meet industry demands.

  • AF system with excellent tracking capability and near-silent operation

    Equipped with a linear motor HLA (High-response Linear Actuator), the Sigma AF Cine Line captures intense movements in action scenes, rapid focus shifts in gimbal or handheld shooting, and unpredictable moments in documentaries without missing a split second, providing reliable support for filmmakers in various shooting situations.
