Sigma 50mm T1.5 FF High Speed Prime (ft) Overview

Sigma's FF High Speed Prime Lenses combine the same high-quality optics and mechanics of their Global Vision still line in a cine-oriented design. This 50mm Canon EF prime is a mid-range focal length in the series, offering full-frame sensor coverage, 6-8K resolution, and a T1.5 aperture in a compact, lightweight form; it is also available in PL and Sony E-mounts. Electronic contacts in the mount provide lens data communication between the lens and the camera. A common 95mm front diameter and similar physical attributes across the lens line make it easier and quicker to mount lens accessories such as matte boxes, follow focuses, and lens control motors.

The 9-bladed iris produces pleasing out-of-focus bokeh effects and ghosting and flaring have been minimized. Color reproduction is standardized for easier color correction. Each lens in the range offers consistent lens gear positions and 180° of focus barrel rotation. The FF High-Speed Primes also feature a clickless iris with linear markings, dampeners on each gear ring for silent operation, industry-standard 0.8 module gear pitch, and engraved markings for durability. Focus marks are in feet with select marks in luminous paint for easy visibility in low light.

To relieve stress on your camera's lens mount, a support foot is built into the dust- and water-resistant metal lens body. If you wish to fit your FF High-Speed Prime lens to a different camera, the Canon EF and Sony E mount versions can be converted from one to the other by an authorized Sigma service center (not available for PL mounts).

Features
Focus marks are in feet with select marks in luminous paint
High image performance covering full frame sensors; suitable for 8K capture
Fast T1.5 maximum aperture aids in shooting with low light levels
Compact, dust- and water-resistant design with a common front diameter of 95mm across the line

Sigma 50mm T1.5 FF High Speed Prime (ft) Reviews

Great lens

By Jonathan
Rated 5 out of 5

If you're doing a prime lens, you'll be fine. The color is good and it's crisp. It has less cat's eye than a canon cn-e and Zeiss CP. A Sigma cine zoom lens is another story. The focus breathing is real!

Preferred over Zeiss CP.2 and Canon CN-E

Pleasantly surprised by this lens. Used to own Zeiss CP.2, and have rented the CP.2 Super Speed 50mm many times, as well as the Canon CN-E lenses. In terms of sharpness, this Sigma easily beats all three of those. In some ways, this is to be expected because those are older lenses, and were designed before 4K was a ubiquitous resolution. If you're still shooting/delivering in HD, then it may not matter. These days, the differences are noticeable in 4k, especially shooting wider than T4. This lens is an amazing value and punches well above her weight. Sharp enough to resolve tack-sharp in 4k, and they claim it's sharp enough for 8k. I won't comment much on color/contrast rendition and character because it's so subjective, but to me it produces a very straightforward and grade-able look and doesn't seem to color the footage much. Also haven't tested/can't comment on lens flare characteristics. Favorite features: -Hardly any chromatic aberration wide open, which is where the other lenses in this range typically fall apart wider than T4. Still very sharp at T2. -Offered in E-Mount with is great for my FS7. -Build quality is as good as one would hope for a lens in this range. -No focus breathing!

Workhorse lens that rivals Zeiss.

We're getting several lenses from this new Sigma Cine line and our first 50mm just showed up. Build quality is like a TANK and these lenses resolve higher with less chromatic aberation or halation than the Zeiss Classic / CP.2 wide open at T1.5. We've tested this ourselves on 2 Scarlet-W REDs and the results were amazing. We're 100% sold on the Sigma lenses for much of our day to day work.

Incredibly Sharp

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!

The Sigma 50mm T1.5 is simply a wonderful lens for me, I use it on every shoot. It works perfect for high-end commercials but is also wonderful for doc shooting since it has a shorter pull than it's competition. It has an 82mm thread on the front allowing early filter additions when using teleprompter and a mattebox can't be arranged. The Glow in the dark paint for the markings was really useful when it came to shooting an independent film in limited lighting. I would recommend a set of Sigma Cine Lenses to anyone who needs to be versatile but is sick of the poor performance of stills glass.

Does the Sigma ART line of smaller (photography sized) lenses feature the same optical performance as these?
Asked by: Blake
When it comes to lenses the quality of the lens can be subjective, but I would say the look/operation of the Sigma 50mm T1.5 Fully Luminous FF High-Speed Prime (EF Mount, Feet) would general be considered superior to the Sigma ART series.
