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 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 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.
