The high-speed Sigma Cine Zoom Line offers a constant aperture of T2 throughout the zoom range, and their outstanding optical performance makes them fully ready for high-resolution shooting in 6K-8K.
At 160°, the rotational angle of the zoom ring is more than double that of a still camera lens, making possible extremely high-precision zooming.
Just like a high-end cine lens, the rotational angle of the iris ring is 60°, and offers smooth control without clicks.
