This smaller version of the 6x6 color-con works great for handheld and gimbal applications. Developed by Camtec to give directors and cinematographers an in-camera tool to vary contrast and hue. Similar in effect to the Arri Varicon, but with the addition of full color, all in a lightweight, low power/heat device. Already in heavy circulation with some of the most well know cinematographers in the world. This unit is something every DP should see.
