New Delhi: 

These launches aim to meet two different kinds of demands. On one hand, there’s growing interest from production houses for precision autofocus in fast-paced and dynamic film shoots. On the other, filmmakers still swear by manual control and cinematic depth. Sigma seems to be trying to serve both.

Sigma is expanding its grip in the cinema lens space with two major product announcements this June. The Japanese lens maker is introducing a new line of autofocus-compatible cinema lenses called the Sigma AF Cine Line, while also unveiling the Aizu Prime Line, the world’s first full range of large-format cine lenses with a constant T1.3 aperture.

The Aizu Prime Line also supports ZEISS eXtended Data, which allows real-time lens metadata to be used in post-production workflows, including VFX.

The Aizu Prime Line, announced for an August 2025 release, is making headlines for one standout spec: it maintains a T1.3 aperture across all focal lengths, from 18mm to 125mm. The first batch of lenses to hit the market includes eight models ranging from 25mm to 75mm. Four more lenses, including ultra-wide 18mm and telephoto 125mm, are expected later.

What makes this line interesting is how it balances modern sharpness with a softer, organic feel. These lenses are designed for consistent performance across full-frame and large-format cinema cameras, offering a 46.3mm image circle and supporting PL and Sony E-mounts. According to Sigma, “the short minimum focusing distance enables striking close-up shots,” while the optical system “delivers a natural, organic look.” All this is wrapped in a compact build, making it suitable for Steadicam and handheld rigs too.

The AF Cine Line is being pitched as a solution for productions that rely on hybrid workflows, from handheld and gimbal shooting to controlled sets. Sigma adds that this new range “integrates cinema-style mechanics and operability,” with features like limited-rotation focus rings and clickless aperture control.

Both lines are built at Sigma’s Aizu factory in Japan.

The second big reveal is the Sigma AF Cine Line. The company is planning two zoom lenses under this line: the Sigma 28-45mm T2 FF (launching in November 2025) and the Sigma 28-105mm T3 FF (coming in Spring 2026).

These lenses build on Sigma’s Art series optics but are re-engineered for cinema. They are compatible with L-Mount and Sony E-mount systems. What stands out is the autofocus performance. Powered by a High-response Linear Actuator (HLA), Sigma says these lenses can capture high-speed scenes with accuracy and near-silent operation.
