Sirui Astra Astra T1.8 1.33x AF Anamorphic 50mm

The Sirui Astra T1.8 1.33x AF Anamorphic 3-Cine Lens Kit brings autofocus to anamorphic shooting for Sony E-mount, with sharp optics and lovely blue flares. It's pricey and AF performance is weak, but the cinematic widescreen results are hard to replicate for the money if you need that built-in squeeze.

In our optical testing, the Sirui Astra lenses landed in the 80th percentile for sharpness and overall image quality. That puts them in strong territory — detail holds up nicely across the frame even wide open at T1.8, and the anamorphic rendering is authentic. You get that signature oval bokeh and the controlled blue streaks when pointed at light sources. For controlled filmmaking, it's a very capable set.

But autofocus is a sore spot. At the 14th percentile, it's one of the weakest AF systems we've seen in this category. It hunts noticeably in low-contrast scenes and can't keep up with even moderate subject movement. The constant T1.8 aperture is nice for exposure, though compared to other cine glass we've tested, it's not a standout — only 19th percentile. Essentially, treat this like a manual focus lens with AF as a backup, and you'll be happier.

Compared to the top competitors in our database, the Sirui Astra kit occupies a strange little niche. Next to versatile zooms like the Nikon NIKKOR Z 18-140mm or the Canon RF-S 18-150mm, it's far less practical for everyday shooting — but that's not the point. The Sigma 10-18mm F2.8 DC DN and Viltrox AF 9mm F2.8 E are APS-C wide-angle lenses that can't match the full-frame cinematic field of view this kit provides. Even the Panasonic Leica 12-35mm, while optically excellent, is on a different mount and lacks the anamorphic character entirely.

What you're paying for here is the look, and in that respect, none of these alternatives come close. If you need an everyday walkaround lens that does a bit of everything, grab one of those zooms. But if you've already got your standard kit and want to add anamorphic widescreen with AF, the Astra set is in a lane of its own.

The Sirui Astra kit ranges from $2,294 to $3,116 across vendors, with the best deal we've seen landing at the lower end. For that money, you're getting a unique set of anamorphic primes with autofocus, which basically no one else offers at this price. If you've priced out renting anamorphic glass, this could pay for itself over a few projects. But it's worth asking yourself how much that AF is worth. Sirui's own manual anamorphic lenses cost a fraction of this, and if you don't need the AF crutch, you'll save a ton. Used markets and rental houses might also offer more rugged cine lenses if build quality is a priority.

If you've been searching for an autofocus anamorphic lens kit for full-frame Sony E-mount, the Sirui Astra T1.8 1.33x 3-Cine Lens Kit is likely on your radar. It bundles 50mm, 75mm, and 100mm focal lengths, all built around that classic 1.33x squeeze for widescreen 2.4:1 footage without any cropping in post. The big selling point here is selectable manual and autofocus, a rarity in the anamorphic world, plus those lovely blue streak flares that scream sci-fi or music video.

At around $2,300 to $3,100 depending on where you shop, it's a serious investment for indie filmmakers or content creators chasing that cinematic look. You get constant T1.8 brightness across all three lenses, which helps in low light, and the optics are genuinely sharp. But our database reveals some compromises: autofocus scored in just the 14th percentile, and build quality and stabilization fall well short of top-tier glass.

That said, if you're willing to work around the quirks, the image this kit puts out is pretty addictive. The oval bokeh, the subtle vertical stretch, and those flares give your footage a character that's hard to replicate with a standard spherical zoom.

If you shoot wildlife, sports, or any fast-action video that demands snappy autofocus and reliable weather sealing, skip this kit and look at something like a traditional telephoto zoom. Run-and-gun documentary shooters who rely on AF might get frustrated, and those who don't need the anamorphic squeeze could save money with high-quality spherical primes like Sigma's Art series. Also, if you're just starting out in video and aren't ready to invest $2,500+ in lenses, there are far cheaper manual anamorphic options to test the waters.

We'd say yes, if you're a Sony E-mount filmmaker who's been waiting for anamorphic glass with autofocus and you don't mind the quirks. The image quality is genuinely good, and the 1.33x squeeze delivers that widescreen feel without the hassle of cropping in post. The blue flares alone will make your footage stand out.

But set your expectations for AF — it's there, but it's more of a convenience than a reliable tool. For serious narrative work, you'll probably be pulling focus manually anyway, and at that point, you could save a chunk of cash with manual lenses. Newcomers to anamorphic might find the workflow adjustments a bit jarring, but if you know what you're signing up for, this kit delivers the look.
