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 Sony E-mount 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 Canon EF and PL 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 and are fully luminous 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).

Related Questions and Answers

Q: 1. When shooting in the set, have you ever thought that you wish the focus of these lenses had a 300-degree rotation instead of 180? Would you mind describing the situation?

A: Large focus throws are imperative when working with significantly shallow depth of field.

Q: 2. Does the lens have a metadata system that sends focus distance and T-stop data back to the camera? (Like Arri LDS)

A: This lens does not have any electronics to send meta data to a camera, like the /i Electronics Technology inside Cooke Cine Lenses.

Q: 3. Love this lens but the ARRI LMB 4x5 mattebox 95mm clamp on adapter ring doesn’t cover the gaps on left and right side. In other words, because the lens hood has the cut outs on the left and right side of the lens, the mattebox adapter ring isn’t deep enough to cover those gaps. So, you have to tape the openings each time you use this lens. Or, is there a better solution? A deeper adapter ring? It needs to remain at 95mm so that it’s easy to swap lenses.

A: As an alternative, you can use a 15mm LWS rod system so you can mount the mattebox using ARLMB4515LWS and ARLMB45TFA. https://www.bhphotovideo.com/c/product/1341037-REG/arri_k2_0013427_lmb_4x5_15mm_lws.html https://www.bhphotovideo.com/c/product/1341036-REG/arri_k2_0014206_lmb_4x5_tilt_and.html

Q: 4. Can the tilt module be removed and the lens be used for other mounts like the normal ff series?

A: No, the tilt ring is not removable but can be locked.

Q: 5. How much does the lens itself weight? The specs only list package weight

A: The PL version weighs 1.5 kg / 3.3 lb.

Q: 6. Will this lens work with the Sony NEX 7?

Q: 7. Will this PL Mount lens work with the RED PL mount fixture?

Q: 8. Can we use this lens with Canon Speedbooster on Red Komodo and not creating vignetting? Thanks.

Q: 9. Can the Xenon handle S35 Sensors at 8k?

A: Yes

Q: 10. Is this lens has got the AF mode? Thanks,
