The Sigma 18-35mm T2 Cine High-Speed Zoom Lens with a Canon EF mount and with focus scales marked in feet provides an image circle that covers Super 35mm-sized sensors. It features a maximum T-stop of 2, and the aperture does not ramp over the zoom range. It shares common lens gear positions with the other lens in the Sigma High-Speed Zoom lineup, which makes for rapid lens changes.

The 9-bladed iris provides round out-of-focus highlights for a natural-looking bokeh. The lens barrel features 180° of rotation from close focus to infinity, the zoom barrel rotates 160°, and the clickless iris ring features 60° of rotation. All three lens control rings are geared with cine-standard 0.8 Mod gears, and the focus scale is marked in feet. The front of the lens is 95mm in diameter with a removable 1/4"-20 support foot that helps support the lens with the aid of a 1/4"-20 rod-mounted lens support (not included).

Color Balance
All the lenses in the lineup are designed to comply with SIGMA's CCI standard simplifying when intercutting between lenses.
Dustproof and Splashproof Design
Sharing the same dustproof and splashproof construction as the SIGMA 150-600mm F5-6.3 DG OS HSM|Sports, each ring and mount is sealed to prevent water and dust from entering.
All-Metal Body Construction
The lens body is made completely of metal to stand up to the rigors of the production day.
Lens Markings
The main lens markings are in luminous paint for easy visibility in low light situations. The intermediate markings are laser-engraved for durability. The focus and zoom markings are readable from either side of the lens.
Lens Front
The lens features a 95mm front diameter for compatibility with a wide variety of matte boxes and incorporates an 82mm front filter thread.
Lens Gears
All three lens gears are standard 0.8 Mod and feature a damper that eliminates metallic sounds when you reach the end of the lens travel.
Support Foot
The lens includes a removable support foot.

Un lente nico para su clase

By Gabriel

Hace pocos meses compr la cmara de cine Ursa mini pro g2 y trat algunos lentes prime, ninguno de ellos me agrad tanto como este de Sigma, porque si tengo que trabajar en un documental que no me permita estar cambiando de lentes constantemente, este 18-35 lo hace todo.

Fantastic lens for documentary shooters

By Alex

I work in documentary and TV, and use this lens on the FS7 with the PL to E-mount adapter. I find it to be an excellent addition to my kit, and I use it frequently for b-roll, as well as following subjects around through changing environments. Being able to ride the aperture in real time (going from outside to inside, or in cloudy weather) is an invaluable quality for documentary shooting. Interestingly, using this with the PL to E-Mount adapter on the FS7, the minimum focusing distance decreases to about 4 inches. Yes, you read that right. I don't know the physics behind it, but something is going with with the adapter to allow it to close-focus substantially more than advertised. This has been extremely useful! Image quality is excellent. It doesn't have the personality as the big name prime lenses; I'd characterize it as a clean, neutral looking image. But for the versatility you get, it has no competitor. For those complaining that this is just a stills lens I'd ask them to consider that the cinema version has proper focus marks, gears, declicked aperture, and build quality that will last a lifetime. Overall this is a fantastic lens, and I'd recommend it for anyone looking to up their game without spending a fortune on a set of primes, or that is working in doc/TV and wants to simplify their kit.

This Cine lens is legendary

Anyone who uses a lot of cine glass knows that the 18-35mm Sigma Cine is legendary for into film makers. Please ignore the other 2 star review as this person clearly doesn't understand the value of lenses. The lack of LDS makes this lens actually "affordable", and speaking of which, is considered CHEAP for the quality of the optics and build. A lot of people are ordering entire era of primes and zooms for RED cameras (ourselves included) for a reason. Sigma Cine lenses are arguably the best value for the superb quality in the industry right now.

Photo lens with Cinema gears

1. Noticeable focus breath . 2 . None Lens Data System ( LDS ) that now very need for post - production works with augmented reality 3. Too overpriced ( " cinema " version with lens gear ) Version for photo with EF ( about $700 ) mount much better for use with RED . Really .

Excellent Image, Practical Function

By Cary

After a year of adapting Nikon glass, using cannon photography lenses, and trying out a few Rokinon primes, I couldn’t be more elated with the results I’m getting from this lens. Having 18-35mm and all the focal lengths between, covered in a single lens is great. The image quality is truly great, but more importantly, it’s soooooo much easier to use than still photo lenses. I’ve already heard the complaints of, “but it’s the same glass as the art series lens, just in a cinema housing!” I don’t know if this is 100% true. My brother and I (Curtis Judd) will be doing a side by side comparison soon with matching Ursa Mini Pros to see if that’s true. Yes, the extra $3000+ for this lens is steep, and yes, I’ve heard it’s the same glass as the art series, but for me in my particular applications, function is the second priority right after image quality. The quality of my projects (ranging from corporate, to real estate, music videos, documentary, and tv commercials) has significantly improved with having a proper range on my focal ring. Historically, as my quality improves, so doesn’t client base. A few other wonderful things about this lens: sigma does not advertise it as being par focal, though after working with it for a week, I have to say, it’s pretty close. If I pull focus at 18mm and zoom to 35mn, the focus holds strong till about 28mm & then it goes a little soft Breathing is minimal on this lens, which I can’t say for the matching 50-100. Another delightful surprise is that my UMP4.6k is able to read and display the aperture via electronic contact points on the lens, so you don’t have to rely solely on the markings on the barrel of the lens.

I just started using the Sigma FF lenses and shot in a very humid location. No internal condensation seen. These lenses have a much higher resolution as far as sharpness and critical focus goes as compared to my previous cine style lenses. Robust build to say the least. I haven't noticed any chromatic aberration at all. Looking forward to using these on feature work!

I just received mine & my previous answer stands. It goes soft around 30mm if I have a tight focus at 18mm & zoom. Definitely not parfocal, but definitely a beautiful lens.

Will this work on a 1dx mark ii for video?
Asked by: Broden H.
This lens is meant to cover Super35 which is a 1.6x crop of full-frame. The 1DX Mark II's 4K is a 1.4x crop. Therefore this lens cannot cover it. If you were to mount it on the camera, 35mm will probably be fine but zooming out the 18mm, you would definitely get vignetting. We suggest using full-frame lenses for the 1DX Mark II 4K recording.

What is the difference between this lens and the sigma 18-35 that is much cheaper?
Asked by: James
This cinema lens is manual focus only, has gears, greater throw, accurate markings and more robust housing made with finer tolerances. This are specifications that come into play on higher level video productions particularly ones that are working day to day with a crew. For one man band personal video it could be overkill.

Is there a version with a Cooke/I lens data port?

Is there a version with a Cooke/I lens data port?
Asked by: Philipp
No. The lens would have to be serviced in order to do so. Sigma Burbank supports a lens conversion service that will convert passive PL mount Sigma Cine Primes to a /i PL mount. If you find yourself in need of amplifying your workflow with metadata, then the conversion service will allow that without needing to buy brand new lenses. If you’re interested in the lens conversion service or wish to know pricing then please reach out to: Sigma Burbank Service Department 213-699-0561 | [email protected]
