DNP  Red Motion Mount handson

Red announced its new Motion lens mount prior to opening its booth at NAB, and now we've had a chance to see this guy in action. The mount, which is compatible with the company's Epic and Scarlet cameras, is meant to fix the CMOS rolling shutter problem. The Motion includes a liquid crystal shutter that's placed in front of the main sensor and is timed to engage when the sensor is fully open. It also adds up to 8x neutral density, which can be enabled electronically through the camera UI with 1/100-stop precision. In a demo at Red's NAB booth, the camera captured every flash of a strobe -- without the new mount, some flashes would likely slip through the cracks. It's set to ship for $4,500 in the fall (or possibly this summer), and will be available with Canon EF or PL mounts. You can see it in action today in the hands-on demo after the break.
