Sigma 20mm T1.5 Fully Luminous FF High-Speed Prime (Canon EF, Feet)
Key Features
  • Covers Full Frame Sensor Size
  • Canon EF Mount
  • Fully Luminous Marks in Feet
  • T1.5 to T16 Aperture Range
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 20mm Canon EF mount prime is a wide focal length in the series, offering full frame sensor coverage, 6 to 8K resolution, and a T1.5 aperture in a compact, lightweight form; it is also available in Sony E and PL mounts. What sets these lenses apart from the standard Sigma High-Speed Primes is fully luminescent markings. When shooting in dim or dark environments, focus pullers and camera operators will be able to easily discern lens markings without the use of a possibly distracting lens light. 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.

Sigma 20mm T1.5 FF (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 20mm Canon EF mount prime is a wide focal length in the series, offering full frame sensor coverage, 6 to 8K resolution, and a T1.5 aperture in a compact, lightweight form; it is also available in Sony E and PL mounts. What sets these lenses apart from the standard Sigma High-Speed Primes is fully luminescent markings. When shooting in dim or dark environments, focus pullers and camera operators will be able to easily discern lens markings without the use of a possibly distracting lens light. 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).

Features

Sigma 20mm T1.5 FF (ft) Reviews

Well made, beautiful lens

I have both the Sigma 20mm and 105 mm High Speed primes and couldn't be happier. The construction is solid and the glass is beautiful sharp and has a nice warmth to the bokeh. Worth the investment.
