Use Quantum's Freewire 2-Step Motor Drive Cords to keep your camera meter and focus function continuously "on" (as in pressing the shutter button half-way). Your camera will be ready for instant shutter release. Or, select motor drive "delay" to command a camera to "wake up", focus and meter, then release the shutter.
Compatible with Pentax cameras that use the Cable Switch F; e.g. PZ, ZX and SF 35mm cameras and 645 & 645N Series Cameras (does NOT work with 645N "II" cameras).
