Designed for professional filmmaking, the Sigma T1.5 FF High-Speed 5 Prime Lens Kit offers a variety of ways to shoot a scene. It includes five prime lenses with a fast aperture of T1.5. These lenses can be used with Sony E-mount mirrorless cameras. They have dedicated control rings for focus and iris. At the end of each ring, a dampener is fitted to suppress the metallic noise. The clickless iris ring also turns smoothly to prevent unwanted sounds. All the lenses have a 9-blade diaphragm that produces cinematic bokeh in the background. The 0.8 module gear pitch of the control ring enables the use of a follow focus unit. A variety of matte boxes or lens motors can be fixed to the lens' 95mm front diameter. The lens comes with a dust- and moisture-resistant metal body that follows the tradition of Sigma's renowned sports lenses. The included case has foam inlays that protect the lenses from impacts and bumps during transportation.
