This cine lens is designed to maintain focus as you zoom in or out. The Catta line reproduces accurate color and features a smooth focus/defocus transition. It features a wide T2.9 to T22 aperture, a 16-blade iris for a smooth bokeh, and a long 75cm close focus range.
True to its cine design, it has a focus rotation of 270°, a 100° zoom rotation range, and a 75° iris rotation range. The lens features a Sony E-mount, and it can be easily interchanged with optional RF, L, X, and Z mounts.
