A modern full-frame cine prime set built for consistent speed and handling. Sigma’s Aizu primes deliver a uniform T1.3 across the range with a balanced, organic image, long cine throws and matched 95 mm fronts—ideal for fast swaps on set. Available in PL, they bring high resolution with a smooth character and tight unit-to-unit consistency.
Overview
- Large-format cine primes with consistent T1.3 across focal lengths.
- Balanced “modern + organic” rendering designed specifically for cinema use.
- 95 mm front diameter, 0.8-pitch cine gears; long focus rotation.
- Close-focus capability around 1 ft on certain focals (model-dependent).
- Full-frame / large-format coverage (LF).
- Consistent housing & gear positions for quick re-rigging.
- Built in SIGMA’s Aizu facility to tight tolerances.
Use Cases
- Narrative and commercial shoots needing a fast, matched T1.3 set.
- Gimbal/handheld work where identical fronts and gear positions speed lens changes.
- Low-light scenes and shallow-DoF portraits without resorting to heavy filtration.

Exploit uniform T-stops
With T1.3 across the set, lock exposure once and swap focals quickly—handy on fast company moves or steadicam days.
Control the character
Shoot near wide open for smooth fall-off and separation; stop down slightly to tighten micro-contrast while keeping the balanced look.
Pre-mark your builds
Match motor positions and matte-box spacing for each focal; the shared 95 mm fronts and gear placement keep swaps under a minute.
Focus discipline
The long throw rewards proper marks—use a lightweight wireless FF on gimbal/handheld for precise eye-line pulls.
Close-focus creatively
The short minimum focus on certain lenses makes tight inserts practical without dioptres—great for product or hands.
