Sigma AF Cine 28-45mm T2 FF and 28-105mm T3 FF: 2026 Review

Quick overview: Sigma AF Cine 28-45mm T2 FF and 28-105mm T3 FF are the industry's first autofocus cinema lenses, combining professional cinematic construction with a silent AF drive. The 28-45mm T2 FF has already been available since November 2025, while the 28-105mm T3 FF is planned for spring 2026 for L-Mount and Sony E-mount mounts.

Sigma has done something that seemed impossible not long ago - it created full-fledged cinema lenses with autofocus that do not compromise either optical quality or professional-use ergonomics.

AF Cine Line is not just photo lenses in a cinematic housing. It is a fundamentally new concept developed by engineers in Aizu, Japan, specifically for modern film production, where documentary shoots are combined with scripted projects, and versatility is needed without sacrificing quality.

Sigma AF Cine 28-45mm T2 FF: A compact all-rounder

The first lens in the line has already been available since November 6, 2025. The 28-45mm T2 FF is based on the optical design of the Art series but received fully redesigned mechanics and an autofocus system.

The T2-T22 aperture range provides enough brightness for most shooting scenarios. The compact form factor makes this zoom ideal for gimbals, Steadicam, and handheld work, where weight is critical.

Key specifications of the 28-45mm T2 FF

Sigma includes the SF-91 support foot, LCF-82 IV front cap, and LCR III rear cap in the package - everything is ready to use right after unboxing.

Sigma AF Cine 28-105mm T3 FF: Maximum versatility

The second lens in the series is planned for spring 2026. The 28-105mm T3 FF offers a 3.75x zoom ratio - a rare range that covers everything from wide angle to medium telephoto.

Unlike most cinema zooms, where a wide range means compromises in sharpness, this lens is based on the popular DG DN Art 28-105mm - one of Sigma's sharpest zoom lenses.

The 12-blade aperture provides smooth bokeh, while the T3-T22 range remains sufficient for professional work even in difficult lighting.

Why autofocus in a cinema lens matters

Graham Sheldon, an ICG Local 600 cinematographer, worked with both lenses in extreme conditions - from Chornobyl to Alaska and the Philippine jungles. His conclusion is clear: high-quality autofocus in a cinematic body opens up possibilities that previously required large budgets and additional assistants.

Traditional shooting scenarios with pure manual focus remain available. But when you need to react quickly to unpredictable action in the frame - documentary interviews, action scenes, handheld shooting - AF becomes not just a convenience, but a necessity.

Technical features and innovations

Both lenses are equipped with an AF/Manual switch, which allows the operating mode to be changed instantly depending on the scene. The HLA (High-response Linear Actuator) system provides accurate and almost silent focusing with reliable subject tracking.

The optical coating is designed for work with full-frame sensors, while the resolving power is sufficient for 8K shooting without loss of detail at the edges of the frame.

Who these lenses are for

AF Cine Line is ideal for:

• documentary cinematographers working solo or in small teams

• scripted cinema with a limited budget for assistants

• commercial shoots where setup speed is important

• hybrid projects (cinema + photo) with a single set of optics

• reality shows and live production

Sigma is not trying to replace traditional primes or heavy cinema zooms. This is an addition to the ecosystem that covers scenarios where filmmakers previously had to choose between quality and speed.

Availability and mounts

Both lenses are available in two mount options: L-Mount (standard and metric) and Sony E-mount (standard and metric). This covers the main full-frame cinematic cameras - Panasonic, Leica, Sony FX, and Alpha.

According to Sigma Corporation's official announcement from June 4, 2025 (the development announcement date), the 28-45mm T2 FF went on sale on November 6, 2025, while the 28-105mm T3 FF is expected in spring 2026.

Should you wait for the 28-105mm or buy the 28-45mm now?

It depends on your priorities. The 28-45mm T2 FF is about compactness, T2 brightness, and availability right now. If your main work is interviews, indoor scenes, or gimbal shooting, this lens covers 80% of needs.

The 28-105mm T3 FF is about versatility. One zoom instead of two or three primes. It is ideal for documentary work, travel shooting, and situations where there is no time to change optics. But you will have to wait until spring 2026.

Many cinematographers plan to buy both - as a powerful pair that covers almost the entire range of scenarios without the need to carry several lens cases.

Frequently asked questions (FAQ)

When can you buy the Sigma AF Cine 28-105mm T3 FF?

Sigma has officially announced the launch for spring 2026. The exact date has not yet been announced, but April-May 2026 is expected.

Does autofocus work as well as on photo lenses?

Yes. AF Cine Line uses the same HLA system as the DG DN Art series, with excellent tracking and almost silent operation suitable for sound recording on set.

Which cameras are supported?

All full-frame cameras with L-Mount (Panasonic S1H, S5 II/IIX, Leica SL2-S) and Sony E-mount (FX3, FX6, FX9, A7S III, A1). Metric versions have focus rings with metric scales and different focus rotation ranges.

Can these lenses be used for photography?

Technically, yes, but T-stops and cinematic mechanics make them inconvenient for photography. For photo work, it is better to use the corresponding DG DN Art models.

What is the difference between the standard and metric mount versions?

Metric versions have focus rings with markings in meters (instead of feet).

Is a case included?

No. The package includes front and rear caps, as well as the SF-91 lens support foot. The case must be purchased separately.

Conclusion

Sigma AF Cine 28-45mm T2 FF and 28-105mm T3 FF are not an evolution. They are a revolution in the approach to cinematic optics.

For the first time in history, autofocus does not mean a compromise in image quality or ergonomics. For the first time, you can get Art-series sharpness, cinematic mechanics, and reliable AF in one body.

If your work requires speed and flexibility without sacrificing quality, these lenses are worth considering.
