Sigma is expanding its hybrid cinema lens lineup with the release of the AF Cine 28-105mm T3 FF zoom lens. Building upon the optical foundation of the company’s 28-105mm F2.8 DG DN Art lens released in , the new lens is specifically engineered for filmmakers, offering autofocus capabilities alongside cinema-focused ergonomics.
The AF Cine 28-105mm T3 FF is the second lens in Sigma’s AF Cine Line, following the 28-45mm T2 FF, which began shipping in . Both lenses were initially announced in , representing Sigma’s entry into autofocus-compatible cinema lenses. The core design philosophy centers around leveraging the proven optical performance of Sigma’s Art series lenses while adding the features and functionality demanded by professional cinematographers.
According to Sigma, the 28-105mm T3 FF offers the same image quality as the still photography-focused 28-105mm F2.8 DG DN Art lens. However, significant modifications have been made to accommodate the needs of video production. These include a limited-rotation ring for intuitive manual focus, near-silent autofocus operation, and 0.8M pitch gears for compatibility with existing follow focus systems. External indicators on each ring facilitate seamless manual operation, and the aperture ring features clickless movement – a crucial feature for smooth exposure changes during recording.
The lens’s design incorporates an advanced optical system intended for “outstanding image rendering.” Sigma emphasizes the professional-grade mechanical design and operability, alongside an autofocus system with excellent tracking capability and quiet operation. The lens is described as a “hybrid” solution, bridging the gap between the convenience of autofocus and the precision control expected in a cinema lens.
Physically, the Sigma AF Cine 28-105mm T3 FF measures 157.9 millimeters (6.3 inches) in length and accepts 95mm front filters. The lens does exhibit a change in length during zooming, a characteristic common to many zoom lenses.
The development of the AF Cine Line represents a strategic move for Sigma, aiming to provide filmmakers with a versatile and high-performance lens option. The lenses are designed to handle a variety of shooting styles and on-set environments, addressing challenges traditionally faced when adapting still lenses for cinema use. By integrating autofocus with cinema-grade mechanics, Sigma seeks to expand the possibilities of visual expression and streamline the filmmaking process.
The Sigma AF Cine 28-105mm T3 FF will be available in both L-Mount and Sony E-mount configurations. While pricing was revealed recently, specific details regarding availability beyond the launch date were not immediately available.
Sigma’s approach with the AF Cine Line is notable for its reliance on existing optical designs. By building upon the success of the Art series lenses, the company is able to leverage proven performance while focusing development efforts on the cinematic features that differentiate these new lenses. This strategy allows Sigma to offer a compelling combination of image quality, autofocus functionality, and professional operability to the filmmaking community.
