Sigma has added three lenses to its Aizu Prime Line of large-format cinema glass: the 21mm T1.3 LF, 100mm T1.3 LF and 125mm T1.3 LF. Each is available in PL or Sony E-mount.
Aizu Prime Line
The line now counts 11 lenses. Sigma launched the first eight in 2025 at 25 mm, 27 mm, 32 mm, 35 mm, 40 mm, 50 mm, 65 mm and 75 mm, all built around the same T1.3 maximum aperture. The three new focal lengths stretch the set in both directions, from ultra-wide to short telephoto. An 18 mm is still on the way.
That reach matters more than the spec sheet lets on. A matched set running 18 mm to 125 mm handles most of a narrative shoot day without forcing a swap into a different lens family halfway through.
VistaVision
The Aizu primes throw a 46.3 mm image circle. Full-frame and Super 35 sensors are covered easily, but large format is the real target here. An Arri Alexa LF in Open Gate fits inside that circle, as does VistaVision.
The lenses also support Cooke /i Technology and ZEISS eXtended Data, which streams lens metadata to the camera while you roll. For anyone handing footage to a VFX team, that means distortion and shading correction data ships with the plate instead of getting solved after the fact.
Consistent look
T1.3 across the entire line buys shallow depth of field and real latitude when the sun goes down. Sigma says the glass holds modern sharpness while avoiding “rigid or harsh depictions to give a natural, organic look.” Distortion and focus breathing are kept in check, and color balance, contrast and flare behavior are matched from one focal length to the next. Cutting from the 35 mm to the 100 mm inside the same scene shouldn’t announce itself.
Other features
Fast cinema primes tend to be heavy. Sigma says these aren’t, which should keep them workable on a gimbal or Steadicam without rebalancing the rig every time the lens changes. Minimum focus distances are short enough for tight close-ups. The focus rings offer a wide rotation angle for precise pulls, and the aperture rings space the stops evenly.
What we think
Aizu is a serious set. Once the 18mm arrives, twelve lenses will cover 18 mm to 125 mm, and the spacing between 18 mm and 50 mm is tight enough that you’re essentially building a zoom shot by shot. Consistent housing dimensions and matched ring placement mean an AC isn’t relearning the glass on every swap.
Then there’s the price. At $9,799 a copy, a full set runs north of $100,000. That’s rental house money, not owner-operator money, and rental houses are almost certainly where most shooters will meet these.
Pricing and availability
All three lenses arrive in November at $9,799 each.
