Sigma has introduced three new Aizu Prime cinema lenses as the lineup grows: the 21mm T1.3 LF, 100mm T1.3 LF, and 125mm T1.3 LF. These additions extend the range of their existing T1.3 lenses, enhancing a lineup that already spans from 25mm to 75mm.

Released models are praised for their sharpness and unique flare characteristics, offering professionals more creative options. As this series evolves, the consistency across lenses means colors, contrast, and bokeh remain uniform, ensuring smooth transitions between shots. Originally announced in June 2025, the series also includes an 18mm lens, still in development.

Innovative Design for Cinematic Consistency as Sigma Advances

These new lenses maintain a balance of modern sharpness with an organic look. Sigma highlights their elegance and minimized focus breathing, important factors for dynamic scenes. “They deliver a natural appearance without harshness,” Sigma states, making them suitable for various visual styles. As the company broadens its offerings, they aim to provide more options for filmmakers.

PetaPixel has extensively tested these lenses, with positive feedback on their unique combination of clarity and character. According to Jordan Drake from PetaPixel, “that’s a rare combination, especially at this price.”

The lenses offer a φ46.3mm image circle, accommodating full-frame sensors and some large-format cameras like the Arri Alexa LF Open Gate. Tests on the Fujifilm GFX Eterna 55 also showed success as their collection further expands.
