Sirui Saturn RF50B-A 50mm T2.9

The Sirui Saturn 50mm T2.9 is a featherweight full-frame anamorphic that delivers the cinematic squeeze for under USD 500. Stabilization is a standout at the 81st percentile, and the 465g build makes it gimbal and drone ready. Manual focus and a 900mm minimum focus distance are the trade-offs, but for the price, it's a fun and capable entry into anamorphic shooting.

Optically, this lens sits at the 68th percentile in our database. That's solid, not spectacular. The 17 elements in 12 groups do a decent job controlling chromatic aberration, and the 10-blade diaphragm keeps bokeh reasonably smooth. But the minimum focus distance of 900mm is rough. You're not getting close-up shots with this thing. The T2.9 to T16 range gives you some flexibility, though the aperture sits at the 44th percentile, which means it's middle of the pack. Stabilization is where it surprises, landing at the 81st percentile. That's genuinely helpful for handheld and gimbal work. The manual focus ring has a 120-degree rotation, which is short for precise pulls but fine for run-and-gun shooting.

Stacked against the Sigma 18-50mm f/2.8 or Tamron 17-70mm f/2.8, this Sirui is a completely different animal. Those are versatile zooms for hybrid shooters. The Saturn is a specialty cine lens. The Viltrox 35mm f/1.7 gives you autofocus and a faster aperture for less money, but it's spherical and won't give you that anamorphic squeeze. The Panasonic Leica 12-35mm and Nikon Z 17-28mm are both sharper and more practical for everyday work. But none of them produce oval bokeh or horizontal flares. If you want the anamorphic look on a budget, the Sirui is basically in a class of one here.

At USD 499 in the US, this is one of the cheapest ways into full-frame anamorphic territory. The EUR pricing is all over the place though, ranging from EUR 439 to EUR 549 across four listings in Germany, Spain, France, and Italy. If you're in Europe, shop around. The lowest EUR 439 listing is the one to grab. For what you get, a lightweight carbon fiber anamorphic with a 1.6x squeeze, the value proposition is strong. It's not a perfect lens, but it's a fun one, and that counts for a lot when you're chasing a specific look.

The Sirui Saturn 50mm T2.9 is a full-frame anamorphic lens that squeezes a 1.6x cinematic look into a package under 500 grams. That's genuinely wild for this category. Carbon fiber construction keeps it light enough for gimbals, FPV drones, and handheld rigs without your arms filing a complaint. It's manual focus only, which is expected for cine glass, but worth knowing before you click buy.

At 50mm with a 1.6x squeeze, you're getting the horizontal field of view of a 22mm spherical lens. That means wide, dramatic shots with oval bokeh and horizontal flares. The T2.9 max aperture isn't the fastest thing out there, but it's workable for most narrative and commercial work. This is a specialty tool for people who want the anamorphic look without selling a kidney or hiring a focus puller.

Skip this if you need autofocus, weather sealing, or close-up capability. The AF score is a brutal 14th percentile, and the 900mm minimum focus distance means no detail shots. If you're a hybrid shooter who bounces between photos and video, a standard zoom like the Sigma 18-50mm will serve you better. And if you're shooting in wet or dusty conditions, the lack of weather sealing is a real liability.

Buy this if you're a filmmaker or content creator who wants the anamorphic look without spending five figures. It's light enough for gimbals and drones, the image quality is solid, and the price is right. The manual focus and 900mm minimum focus distance mean you need to plan your shots. But if you're shooting music videos, short films, or stylized commercial work, this lens delivers a look that's hard to replicate with spherical glass. The 4.5-star rating from 22 reviews backs that up.
