Red has just announced the Red Motion lens mounting system for Epic and Scarlet motion camera systems that'll eliminate one of their chief snags: the dreaded CMOS rolling shutter. Though details are scant, it seems it'll do that in a similar manner to the Tessive system (see More Coverage), where a second liquid crystal shutter is placed in front of the main sensor and timed by the camera's UI to engage only when the camera's CMOS is fully "open." That'll help eliminate artifacts like skew / judder in pans, repeating motion artifacts (think distorted propellers) and flicker from lights or displays, among others. The mount also brings a built an 8x electronic ND filter adjustable to 1/100th of an f-stop, partially negating the need for a matte-box in bright lighting situations. The Red Motion's drawback is that it'll cost you a stop of speed even when the ND is off, meaning you may have to change to a classic mount in low-light situations. Red's showing it now at its NAB booth-cum-factory and it'll ship out this fall in PL-mount form (with a Canon mount arriving later) for $4,500. Check the source for more discussion.
