Sirui Venus 50mm T2.9 1.6X Full-Frame Anamorphic 50mm
Its 1.6x squeeze factor transforms standard 16:9 capture into an immersive 2.8:1 aspect ratio with oval bokeh and characteristic horizontal blue lens flares. The 1074g all-metal barrel and 31mm close-focus distance provide rugged, detail-oriented handling despite being manual focus only. Best for independent filmmakers on Sony E-mount chasing anamorphic widescreen aesthetics and sci-fi flare effects.

Факты
Performance
The 1.6X squeeze factor is the star here. Point this thing at a light source and you get those horizontal sci-fi flares that make footage feel expensive. The 10-blade aperture keeps bokeh smooth and oval, and the 16 elements in 13 groups do solid work for contrast and color. Macro performance is shockingly good for a cine lens, landing in the 97th percentile in our database. But sharpness is a mixed bag. A couple of owners report muddy, soft images on high-res Sony bodies, while most praise the clarity. That inconsistency is worth noting if you're pixel-peeping on an a7RV.

vs Competition
The obvious rival is Sirui's own Saturn 50mm anamorphic, which is smaller and lighter but gives up some of the Venus's full-frame coverage and macro chops. If you're on an APS-C body, the Saturn makes more sense. Against traditional spherical primes like the Sigma Contemporary 18-50mm f/2.8, the Venus is a completely different tool. You're not buying this for autofocus or versatility, you're buying it for the anamorphic look. And for that specific job, nothing in this price range touches it.

Value & Pricing
Pricing is all over the place right now. We're seeing USD 299 to USD 487 across two US listings, which is a massive spread for the same lens. At the low end, this is an absolute steal for anamorphic glass. At the high end, you're creeping into territory where you should consider the smaller Saturn version or save for a used higher-end option. Shop around and don't pay the top price.

Overview
The Sirui Venus 50mm T2.9 1.6X is the budget anamorphic lens that actually delivers the cinematic goods. You get that widescreen 2.4:1 or 2.8:1 aspect ratio, oval bokeh, and signature blue flares without selling a kidney. It's manual focus only and built like a tank, but for indie filmmakers who want the anamorphic look on a full-frame RF or E mount body, this is the entry point that makes sense.
Common Questions
Q: Does this lens have autofocus?
No, it's manual focus only. That's standard for cine lenses and actually preferred for video work, but if you need AF for stills or gimbal work, look elsewhere.
Q: What aspect ratio will I get with this lens?
With the 1.6X squeeze, shooting 3:2 gives you 2.4:1, and 16:9 gives you a super wide 2.8:1. You'll need to desqueeze in post, but the result is that IMAX-style widescreen look.
Q: Is this lens weather sealed?
No weather sealing here. It's a solid metal build, but don't take it out in rain or dust storms without protection.
Who Should Skip This
If you need autofocus, lightweight handling, or consistent tack-sharp images across every copy, this isn't your lens. Go grab a solid spherical prime like the Sigma Contemporary 18-50mm f/2.8 instead. And if you're on APS-C, the smaller Sirui Saturn makes more sense than lugging this 1074g beast around.
Verdict
If you want real anamorphic footage without spending five figures, the Sirui Venus 50mm T2.9 is the lens to get. It's not perfect, sharpness can be copy-dependent and the weight is real, but the image character is undeniable. For indie filmmakers, music video shooters, and anyone chasing that widescreen cinematic feel, this is a clear buy. Just inspect your unit when it arrives and shop for the best price.
