The SIRUI IronStar 35 mm T1.9 combines full-frame coverage with a 1.5x anamorphic image for wide establishing shots and architecture. A neutral flare version, it gives cinematographers geared manual control and a consistent visual character alongside the other IronStar lenses.
The 1.5x anamorphic image
A constant 1.5x squeeze captures a wider horizontal field than a conventional spherical lens and produces an elongated bokeh shape after de-squeezing. The result is useful for creating visual depth in dialogue, storytelling and atmospherically lit scenes.
Cine mechanics and matching lenses
The lens is supplied with an interchangeable PL/EF mount design for use across compatible cinema camera systems. A 270° focus throw, cine gears and unified dimensions are designed for follow-focus operation and efficient lens changes. This version features neutral flare rendering. Minimum focus distance is 0.65 m.
The 1.5x horizontal compression widens the frame after de-squeezing while retaining the chosen focal length’s vertical perspective. Matching mechanics and colour rendering make it easier to move from wider scenes to close-ups in a coordinated IronStar set.
