Sirui Astra T1.8 1.33x AF Anamorphic 50mm

★★★★★ 5.0 (1)

A constant T1.8 aperture across three anamorphic focal lengths—50mm, 75mm, and 100mm—on full-frame Sony E mount with selectable autofocus enables 2.4:1 widescreen shooting without cropping. Neutral streak flares and a consistent 44mm image circle deliver a unified, subtle cinematic look, while the shared 67mm filter thread streamlines rig changes. This kit is ideal for indie filmmakers and Sony hybrid shooters who need a compact, autofocus-capable anamorphic set for run-and-gun video with natural flare character.

The 30-Second Version

Sirui's 3-lens anamorphic kit brings autofocus and that cinematic stretch to L-mount cameras without the usual vintage hassle. Optics are above average and neutral flares look great, but build quality and lack of stabilization hold it back. At around $2549 if you hunt for a deal, it's a fair price for a specialized creative tool.

Pros & Cons

الإيجابيات

  • That 2.4:1 widescreen look straight out of camera with no cropping. 72nd
  • Selectable autofocus on anamorphic glass is a rare convenience. 71st
  • Neutral streak flares look classy, not cheesy.
  • Lightweight build won't tip your camera rig forward.

السلبيات

  • No weather sealing means these are a gamble outdoors.
  • Build quality feels a bit plasticky for the price point.
  • Stabilization is missing entirely, so handheld video gets shaky fast.
  • The minimum focus distance is frustratingly long.

الأدلة

Performance

Optically, these lenses are solid, landing near the top third of our database for a natural, flattering image. The T1.8 aperture is bright enough for low light, though its ranking is underwhelming compared to modern photo lenses because anamorphic designs always trade some speed for that stretched character. Autofocus is middle-of-the-pack, sometimes hunting in lower contrast, and the close focusing distance of 500mm means you won't nail tight detail shots. Bokeh is soft and oval-shaped, but falls a bit behind the best we've seen in this category. Without stabilization, you'll want a tripod or a very steady hand for video.

vs Competition

Stacked against general-purpose zooms like Nikon's Z 18-140mm or Canon's RF-S 18-150mm, this kit is a completely different animal. Those lenses are versatile for run-and-gun photography, while Sirui's trio is all about cinematic character and a fixed wideness. Compared to other affordable anamorphic options, the autofocus here is a genuine differentiator, but Viltrox or Sigma f/2.8 primes will beat it in sheer light gathering and build quality. You're buying into a specific look, not general usefulness.

Value & Pricing

Pricing is all over the place, from $2549 up to $3492 across vendors, so you definitely want to shop around for the best deal. Even at the low end, it's a serious investment, and the build and sealing omissions sting a bit. But if you're shooting narrative or music video work and want that CinemaScope aesthetic without ancient, heavy glass, the cost is actually reasonable. For three dedicated anamorphic primes with autofocus, this sits in a sweet spot for independent filmmakers who can protect them from the elements.

Overview

Sirui packed three anamorphic primes into one kit, and you get 50, 75, and 100mm L-mount lenses that each open to T1.8. The promise here is that vintage widescreen look without spending a fortune or dealing with massive rigs. They're light, they autofocus, and you can switch between auto and manual focus right on the barrel.

But there's a catch: build quality sits below average for the price, and there's zero weather sealing or stabilization. If you're dreaming of dramatic oval bokeh and neutral streak flares for a narrative project, this kit does deliver. Just don't expect it to feel like a tank or handle a downpour.

Common Questions

Q: What's the widest aperture on these lenses?

Each lens in the kit opens to T1.8, which is fast for anamorphic primes and lets in plenty of light for dimly lit scenes.

Q: Is this kit suitable for handheld, run-and-gun shooting?

Not really, because there's no image stabilization and the lenses aren't weather sealed. You can get away with short handheld takes on a stabilized body, but a tripod or gimbal is the smarter move.

Q: Does the kit produce the classic blue anamorphic flares?

The neutral streak flares are actually much less colorful than the typical blue you see in movies. They're designed to add texture without an obvious color tint, keeping things subtle.

Who Should Skip This

Skip this if you need a lens that can handle rain, dust, or rough handling. Videographers who rely on handheld work or need close-up macro capability will find the lack of stabilization and long minimum focus distance frustrating. If you're just dipping your toes into video and don't care about the de-squeezed aspect ratio, a fast standard zoom will serve you better for far less money.

Verdict

This kit is for L-mount videographers who've been itching to shoot true widescreen without breaking out a reference monitor for de-squeeze. The autofocus makes it more approachable for solo operators, and the flare character is intentionally clean. If you're building a personal cinema kit and can forgive the flimsy exterior, it's a compelling budget entry into anamorphic primes. Just don't expect it to replace a rugged all-rounder.
