Featuring incremental, exact motor position plus tap and move keyframe adjustments. REPEATABILITY Repeat the exact same move over and over again at the same speed or variable speeds depending on the application. DELAY BY DATE/TIME Not going to be around when your move needs to start? No problem. Easily set a date/time or fixed amount of time to have your move begin. kOS takes care of the rest. FLASH MARK/BLOOP Sync up your moves easily via the built-in flash marks with adjustable delay. PRE & POST-PHOTOS (TIMELAPSE MODE) Easily add a series of head or tail photos to your timelapse move.
