Sigma's 105mm T1.5 FF Sony E Mount High-Speed Prime Lens combines the same high-quality optics and mechanics of the Global Vision still line in a cine-oriented design. This 105mm Sony E-mount prime is a mid-range focal length in the series, offering full-frame sensor coverage, 6-8K resolution, features markings in feet, and a T1.5 aperture in a compact, lightweight form; it is also available in Canon EF and PL mounts. A common 95mm front diameter and similar physical attributes across most of 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. Select markings are done 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).
