Sirui announced three new IronStar focal lengths at NAB 2026: a 75mm T1.9, a 100mm T2.8 Macro, and a 135mm T2.8. They join the existing 35mm, 45mm, and 60mm T1.9 primes to complete a full six-lens anamorphic system. All three maintain the 1.5x constant squeeze ratio, share an identical 95mm front diameter, and keep the same gear positions as the rest of the set. Shipping started June 22, 2026, at $999 per lens, or $2,999 for the three-lens kit.
The Three New Lenses, Individually
One correction worth flagging here: Sirui’s official store labels all three as T1.9, but multiple independent sources including Newsshooter and PetaPixel confirm that the 100mm and 135mm are both T2.8. Sirui made this choice deliberately. Keeping both lenses at T2.8 allowed the company to match the 95mm front diameter and identical gear ring positions of the rest of the lineup. For set consistency, especially on a gimbal or Steadicam, that trade-off makes real sense.
What Makes the 100mm Stand Out
The 100mm is the headline lens of this trio. A 0.3m minimum focus distance with 0.5x magnification makes it the first anamorphic macro prime at this price point. Product cinematography, insect close-ups, food shoots — these are workflows where anamorphic rendering has historically required expensive workarounds. The 100mm solves that directly. Close-focus anamorphic with oval bokeh and horizontal lens flare, at under $1,000, is a genuinely unusual combination.
An anamorphic macro at $999. That sentence would have seemed unreasonable three years ago.
Shared Design Across the Full Set
The mid-lens anamorphic element placement is worth noting. Most anamorphic lenses place their cylindrical elements at the front or rear. Sirui puts them in the middle, which keeps the overall size down and reduces weight. Each lens sits at roughly 1kg, which is manageable for handheld use and well within gimbal limits for a lens this focal length.
The 92mm filter thread is the one genuine inconvenience. It is not a standard size. Sirui acknowledges this and includes a VND filter and CPL in the three-lens kit, which is a practical solution. Buying filters separately will take some searching.
Aspect Ratios and What the 1.5x Gets You
The 1.5x squeeze factor sits between the more common 1.33x and 2x options. In 3:2 open-gate shooting mode, de-squeezing gives you a 2.25:1 aspect ratio. In 16:9, it delivers a wider 2.66:1 widescreen. Both are meaningfully cinematic without the extreme distortion that 2x lenses introduce at wider focal lengths. For narrative work, documentary, and commercial production, 1.5x is a versatile choice.
Who These Lenses are for
Yes: Indie filmmakers and small production teams who want a complete anamorphic kit without spending five figures. Cinematographers working on narrative shorts, commercial spots, or documentary work who need consistent gear across a full focal range. Anyone requiring close-focus anamorphic capability on the 100mm.
Worth knowing: The 100mm and 135mm step down to T2.8. Users who need T1.9 across the full set for low-light narrative work will feel that gap at the longer end. The 92mm filter thread requires specific glass. PL and EF mounts only at launch.
Sirui built the IronStar series for filmmakers who want professional anamorphic results without professional-tier budgets. With six primes now covering 35mm through 135mm, the system offers a complete focal range. The new telephoto trio fills the portrait, compression, and close-up gaps that the original three lenses left open. At $999 per lens, they remain among the most accessible full-frame anamorphic primes available anywhere.
