Features
- 3X Zoom RatioThis cine lens covers a very practical zoom range from wide-angle to medium telephoto (28mm to 85mm), which allows filmmakers to go out for filming all in one package. This zoom lens features advanced parfocal design, which allows the focus remains unchanged throughout the zoom range, so the story will be consistent and attractive.
- Step-less ControlAn aperture range of T3.2 to T22 is offered for precise exposure control. The lens features a step-less aperture ring and a long focus throw of 259 for accurate and smooth iris adjustment and focus pulling. The focus ring features a dual scale with both feet and meters, making this lens super nice to operate and use.
- Ingenuity In DetailsWeighs only 2.5kg with an all-metal body, this lens looks super solid and premium. It comes with a custom hard case with PP alloy construction, providing optimal protection for the lens against extreme temperatures, water, dust, etc.

These dropped to ~$1000 on sale and I had to pick one up. Finding a parfocal zoom that performs nicely within a budget price range is hard to do. Although the 28-85 does not have the best wide open performance (T3.2) I found it more than enough when covering events. Parforcal performance is accurate with proper shimming and the image produced when stopped down makes for a great addition to my lens line up. All rings are smooth and nicely dampened. For my use case I am pairing the 28-85 to APSC and Super 35 sensor cameras (BlackMagic & Fujifilm). The elephant in the room with this lens is its size and weight, this is a BIG and heavy lens. I prefer keeping this lens on a shoulder rig as it becomes unruly with a cine saddle/handheld rig. Additionally make sure that you properly support this lens with a screw in lens to rail mount, given its size I would not be surprised to see a snapped lens mount. Another aspect is close focus, I found distances to be reasonable but do not think that you will get any macro level close ups. Distortion is nicely controlled and if using on a S35 sensor the added crop will help keep those elements out of frame/minimized. Overall if you are in the market for a parfocal lens for a budget price (especially useful for events), this should be on your shortlist to at least rent.

We rented this lens for a feature last summer to be paired with the Mars Anamorphic set, I loved it, and when I saw the recent price drop, I pounced. $1064 for this lens feels like I did something illegal. It's big, heavy, and built like a tank. The lens itself is extremely impressive - it looks and feels like a piece of art itself - and the images are fantastic (dare I say instantly cinematic?) - crisp but not with that digital sharpness, and just enough character. The zoom, focus and iris are silky smooth, the focal range covers just about everything I need, and the T3.2 becomes T2.2, with a speedbooster, which is pretty insane for a parfocal cine zoom. Even the case is impressive. I expect to be using this lens, along with the Mars set, for years to come. Great job, Sirui!

Fantastic lens. It captures beautiful images, has excellent build quality, smooth focus, zoom, and aperture rings, and was packaged even better than an Apple product. It is a heavy lens, so make sure you have a decent lens support.

The media could not be loaded. I can't say enough about this lens. For the price, it's a clear steal. I have a lot of Canon lenses I use with my Pyxis 6K cinema camera as well as Rokinon cinema lenses, all purchased through Amazon. But changing lenses during a shoot drives me nuts, especially if I have a complex rig setup. The sir 2885m full-frame Parfocal Zome Cine Lens allows me to use most of my popular mm lenses all in one which frees me up to establish the distances I want to shoot at without swapping out lenses and slowing down the filming process. I've included a handheld run and gun short film shot at dusk. The lens performs flawlessly. I love the feel, quality and look of this lens. It's all metal and it is heavy but I don't feel cheated in the least. It's a real jewel. My rig setup with this lens is a bit busy but once I got use to it, I can't imagine shooting any other way.

I've shot with all types of lenses for the last 20 years. Arri, Zeiss, Angenieux, Cooke, etc. I put together a small kit for myself so I wouldn't have to keep renting for smaller jobs. Ended up going with the Sirui Saturn Primes and this zoom. Can't tell you how happy I am with the purchase. It produces great images and has all the ergonomics and feel of its more expensive predecessors.
