At NAB 2026, SIRUI demonstrated three new additions to their IronStar full-frame anamorphic line with a constant 1.5x squeeze factor. The debuting 75, 100, and 135mm ought to complete the existing ecosystem, and provide users with lenses for mid-to-telephoto coverage. On top of that, the 100mm is a macro, which is a rare find in the anamorphic world. CineD’s Graham Ehlers Sheldon stopped by SIRUI’s booth to take a look at IronStar and talk about the specifications of the freshly added lenses.

Until now, SIRUI IronStar has offered a set of three anamorphic lenses with a 1.5x squeeze factor and exchangeable mounts: 35, 45, and 60mm, all in T.1.9. We talked about this set here, and CineD’s Johnnie Behiri used them for his mini documentary, which you can watch as well. The new additions to the line have the same properties – well, almost, and we’ll talk about it in a moment.   

SIRUI IronStar 75/100/135mm added to the kit

The three focal lengths introduced in this line also have a 1.5x constant squeeze ratio and come with native PL mounts. However, each lens includes an additional EF mount with dedicated tools, allowing users to switch between mounts themselves and ensuring versatility.

The IronStar 75mm is also T1.9, while 100mm and 135mm are in T2.8. Originally, the company wanted to keep the whole series in T1.9. Sonny Liu from SIRUI explains that they decided to change it in order to keep the entire line-up consistent in size. They all feature identical gear positions for fast lens swaps and to ease the process of adjusting the accessories. Each IronStar lens, including the newly added ones, is around 1kg. As Graham adds in the interview: “You definitely know why size consistency is important if you’ve ever had to rebalance a gimbal or a Steadicam.”

SIRUI IronStar 100mm macro

The most curious addition to the IronStar line is a 100mm macro. As Graham puts it, filmmakers are not used to seeing this word on the side of anamorphic lenses. This particular lens, however, promises a 0.3m minimum focus distance, which is super close to the front element and makes it a real macro lens.

Flare characteristics

Just like the entire IronStar series, the newly introduced focal lengths feature oval bokeh, common to anamorphic lenses, and offer two signature anamorphic flare styles – blue and neutral.

While blue is a classic, Sonny explains, the neutral option is becoming more popular among customers. It presents the light in its natural form (meaning it comes out whatever the color of the light source is). Thus, it is subtler and easier to use across different types of projects, including commercials and documentaries.

New SIRUI IronStar available as a set

Just like the first three lenses in the IronStar series, the new three are available as a set. As an additional bonus, the set includes two filters: a VND and a CPL. This is important to know because while the outer diameter of lenses is 95mm, which is standard for the cinema-grade matte box, the inside filter size is 92mm, which is relatively uncommon. By adding the most-used filters to the set, SIRUI makes the lives of its clients a bit easier.

Price and availability

You can find the initial kit with 35 mm, 45 mm, and 60mm here. The newly introduced focal lengths in the SIRUI IronStar series are only available for pre-order right now. The company promises to get them to the market in early summer. Just like the first lenses in the line, the new additions will cost around $1000 per lens.
