Product description NAB 2017: New Cinema Prime Lenses from Sigma Read More dxutdcebrbazbyua 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 PL 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 Canon EF and Sony E mounts. 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 markings 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).
- Focus marks are in feet with select markings 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
