For Full-Frame. This Cooke 18mm T2.4 SP3 Full-Frame Prime (Sony E) is a lightweight, cinema style lens with a true 2.4 aperture that is designed to support Full-Frame sensors.

Cinema Design. This lens’s cine-style aperture and focusing rings boast standard 0.8 mod gears so that you can easily install a follow-focus system, lens motor, or lens-control system, and its common 64mm front diameter lets you use almost any cine-style matte box. It sports a generous 78° of iris rotation and an extended 160° smooth focus throw that gives you accurate focus pulling with almost no focus breathing.

Advanced Optics. The 18mm T2.4’s optics are designed to give you the best possible performance at full aperture while warding off flare, distortion, and spherical aberrations. They’re well-balanced for astigmatism, and they correct for lateral and longitudinal aberrations over the entire image area.

High-Quality Build. The 18mm was designed for a wide range of shooting applications, and it balances comfortably when used with compact cameras. A cam-style focus mechanism ensures smooth adjustments, while large, clear numbers on both sides of the barrel give your focus puller the option of working on either side of the lens.
