The EZ-3 lens is a lightweight telephoto cine zoom that weighs just 2.6kg. It follows the same design principles as the EZ-1 and EZ-2 lenses. It features a 114mm front diameter, a 105mm filter thread, and a quick IRO Technology system for easy conversion between feet and meters. The lens also has a large format option that covers an image circle up to 46mm diagonally, suitable for full-frame sensors. With advanced IRO Technology, switching between FF and S35 formats is quick and doesn’t require changing rings or removing the lens mount.
