Capture wide, cinematic images enhanced by natural neutral flares using the IronStar Series 35, 45 & 60mm T1.9 Full-Frame Anamorphic Lens Set from Sirui. This set bundles a 35, 45, and 60mm lens with a circular polarizer and variable neutral density filter.

  • 35, 45 & 60mm Set
  • Full-Frame | T1.9 to T16
  • Diameter: 95mm
  • Interchangeable EF/PL Mount

The 30-Second Version

This set delivers gorgeous anamorphic images with a fast T1.9 aperture across all three focal lengths—optical quality is top-notch for the price (86th percentile in our database). Build and lack of autofocus might turn off hybrid shooters, but at $2,849 from the right retailer, it's a solid entry into anamorphic filmmaking.

Overview

So you want anamorphic lenses without selling a kidney? Sirui's IronStar set bundles a 35mm, 45mm, and 60mm T1.9, each delivering those organic oval bokeh and cinematic flares that make footage look instantly more expensive. These are full-frame, interchangeable mount (ARRI PL and Canon EF included), and tuned for a neutral flare look rather than wild blue streaks.

They're manual focus only, no image stabilization, and definitely not weather-sealed, so they're aimed squarely at narrative and controlled-set video work. But if you're chasing that widescreen magic, the image quality is the real star here.

Performance

Optically, these lenses sit among the best anamorphic sets we've seen under $5k. Sharpness holds up well across the frame, and the neutral flare coating keeps things subtle rather than gimmicky. Bokeh is smooth but not groundbreaking, right around average for this class. At T1.9, you get enough light for most interiors, though it's not class-leading speed. And manual focus only means you'll want a follow focus system; there's no electronic help here.

Value & Pricing

For a three-lens anamorphic set covering full-frame, the entry price around $2,849 is surprisingly reasonable—especially when single anamorphic primes often cost more. You'll spot deals as low as that from some retailers, so it's worth shopping around. At the high end of nearly $4k, it's less attractive, but if you can grab it closer to $3k, it's a real bargain for indie filmmakers.

vs Competition

Stacked against traditional photo zooms like the Nikon Z 18-140mm or Canon RF-S 18-150mm, the IronStar set lives in a completely different world—manual focus, no stabilization, and triple the price. But for video shooters, its real rivals are other anamorphic sets like the Great Joy 50mm T2.9 or Sirui's own cheaper Venus series. Compared to those, the IronStar offers better optical consistency and a more controlled flare, but you sacrifice some character and speed.

Common Questions

Q: How do I use filters if the thread size is 92mm?

The lens filter thread is 92mm, but the front diameter is 95mm. Sirui includes a circular polarizer and variable ND filter in the set, so you're covered out of the box. For extra filtration, a matte box with 4x5.65" filters or a 92mm step-up ring are your best bets.

Q: Will these work on my mirrorless camera?

Yes, the included PL and EF mounts cover most cinema cameras and DSLRs natively. For mirrorless bodies, you'll need a passive adapter since the flange distance is standard, but there's no electronic communication to worry about.

Who Should Skip This

Skipping autofocus and stabilization means these aren't for run-and-gun shooters, wildlife videographers, or anyone who needs to grab quick shots in changing conditions. If you need a lens that can handle rain or a bumpy gimbal shot without a dedicated focus puller, look at something like a Sony G Master zoom instead.

Verdict

If you're a narrative filmmaker or music video director looking to add authentic anamorphic soul to your work without a five-figure budget, this set is a fantastic starting point. The constant T1.9, interchangeable mounts, and neutral flare give you creative flexibility. Just be ready to rig up a manual focus setup and treat these lenses with care since the build isn't tank-like.
