Sirui Saturn Venus E35 35mm

The Sirui Saturn 35mm T2.9 is a lightweight full-frame anamorphic lens built for gimbal and drone video work. It delivers a cinematic 2.4:1 or 2.8:1 frame with oval bokeh and signature flares, but it's manual focus only and not weather sealed. At USD 499 to USD 804, it's one of the cheapest ways to get true anamorphic character on full-frame.

Optically, this lens is solid but not mind-blowing. It ranks around the 72nd percentile for optical quality in our database, which means it's above average but not leading the pack. The 18 elements in 13 groups do a decent job controlling chromatic aberration, and the 10-blade aperture helps produce those creamy oval bokeh balls anamorphic shooters obsess over. But the bokeh score itself sits at the 43rd percentile, so don't expect the smoothest background rendering you've ever seen. It's good, not great.

Stabilization is a strong point here, landing in the 80th percentile. That's a bit surprising for a manual cine lens, but the light weight and compact size make it easy to balance on a gimbal. You won't get optical stabilization, but the form factor itself is the stabilizer's best friend. Minimum focus distance is 0.9m, which is fine for most narrative work but not ideal if you want to get close to small details. The macro score of 52.1 out of 100 reflects that. For video and cinema work, it scores 50.6, which is respectable but not class-leading. Portrait use lands at 47.8, and wildlife or sports is a weak 34.8, which makes sense given the manual focus and anamorphic squeeze.

The Sirui Saturn 35mm T2.9 doesn't really compete with standard zooms like the Tamron 28-75mm f/2.8 G2 or the Sigma 18-50mm f/2.8 DC DN. Those are autofocus workhorses for hybrid shooters. The Saturn is a specialty tool. If you're deciding between this and a Panasonic Leica 12-35mm f/2.8, you're asking the wrong question. The Panasonic is a versatile everyday lens. The Saturn is for when you want that specific anamorphic look and you're willing to manual focus everything.

Where it gets interesting is against other budget anamorphic options. Sirui's own 50mm and 75mm anamorphic lenses are bigger and heavier. The Saturn 35mm is the lightest full-frame anamorphic they make, and that's its main selling point. The Viltrox 9mm f/2.8 is a completely different beast, an ultra-wide autofocus prime for APS-C. The Nikon Z 17-28mm f/2.8 is a wide zoom with autofocus and weather sealing. None of those give you the anamorphic squeeze. So the Saturn doesn't really have a direct competitor at this price and size. That's both a strength and a warning: you're buying into a very specific look, and there's no autofocus safety net.

Value is tricky here because the price spread is huge. In the US, you can find it for USD 499 at one listing and USD 804 at another. That's a USD 305 gap for the same lens. If you're in Europe, the EUR 671 to EUR 952 range is even wider at EUR 281. The best deal in the US is clearly the lower-priced listing, so shop around before you buy. Compared to traditional anamorphic cinema lenses that can run thousands, this is a bargain. But compared to a standard 35mm prime like a used Samyang or Rokinon cine lens, you're paying a premium for the anamorphic character. Whether that's worth it depends entirely on whether you want that squeezed, flared, oval-bokeh look. If you do, this is one of the cheapest ways to get it on full-frame.

The Sirui Saturn 35mm T2.9 is a full-frame anamorphic lens that sits in a pretty specific niche. It's for filmmakers who want that wide, cinematic 2.4:1 or 2.8:1 look without renting a set of expensive glass. At 422g and about 100mm long, it's shockingly small for what it does. The carbon fiber body keeps things light, which matters when you're throwing it on a gimbal or an FPV drone. Price-wise, you're looking at a spread from USD 499 to USD 804 depending on the vendor, with EUR listings running from EUR 671 to EUR 952. It's not cheap, but it's also not in the stratosphere of traditional anamorphic cinema lenses.

People searching for a 35mm anamorphic lens usually want to know if it's good for run-and-gun video work or if the manual focus will drive them crazy. The short answer: it's built for video first, and the manual focus is part of the deal. You get a 120-degree focus throw, which is decent for pulling focus with a follow focus rig. But there's no autofocus here, and that's a big reason the AF score lands near the bottom of our database. If you're a stills shooter looking for a fast 35mm prime, this isn't your lens.

Is the Sirui Saturn 35mm good for gimbal work? Yes, and that's really the whole point. The 1.6x squeeze factor gives you the horizontal field of view of roughly a 22mm spherical lens, so you get that wide anamorphic frame without a massive front element. The trade-off is that you're manually focusing, and at T2.9 wide open, nailing focus on a moving subject takes practice.

Skip the Sirui Saturn 35mm T2.9 if you shoot stills, need autofocus, or work in rough weather. Hybrid shooters who split time between photo and video will find the manual focus and lack of weather sealing frustrating. If you mostly shoot wildlife or sports, the 34.8 out of 100 score in that category tells you everything. A standard 35mm prime like a Sony FE 35mm f/1.8 or a zoom like the Tamron 28-75mm f/2.8 G2 will serve you far better. Also skip it if you're on a tight budget and don't specifically need the anamorphic look. A used Rokinon 35mm cine lens costs less and is easier to focus.

Should you buy the Sirui Saturn 35mm T2.9? If you shoot video, want the anamorphic look, and already use a gimbal or drone, yes. It's the lightest full-frame anamorphic lens Sirui makes, and the 1.6x squeeze delivers that wide cinematic frame without breaking your back or your gimbal motors. The image quality is good enough for professional work, especially if you're shooting weddings, music videos, or short films where character matters more than clinical sharpness.

But if you need autofocus, weather sealing, or a lens that can double as a stills prime, skip it. The manual focus is a real commitment, and at T2.9, you'll want decent lighting. The price spread also means you need to shop carefully. At USD 499, it's a compelling buy. At USD 804, it's harder to justify. For the right filmmaker, this lens is a lot of fun. For everyone else, it's a niche tool that will gather dust.
