The Sigma T2/T1.5 FF 7 Lens Kit comprises seven fast prime lenses of different focal lengths: 14, 20, 24, 35, 50, 85, and 135mm. All these lenses are built for Sony E-mount mirrorless cameras. They come with independent rings for controlling the focus and iris. These rings have built-in dampeners at the end to reduce the unwanted metallic noise. Additionally, the iris ring has a clickless design that keeps it silent when adjusting the T-stop value. The 9-blade diaphragm produces smooth bokeh quality. Also, the fast aperture contributes to the low-light shooting. The control rings have a 0.8 module gear pitch for allowing the use of a follow focus unit. You may attach industry-standard matte boxes or lens motors to the 95mm front diameter. The lenses have an all-metal body that is resistant to dust and water splashes. The provided carry case ensures convenient transportation with its soft foam inlays and padlock inserts.
