You really have to handle the Quadra HS Flash Head from Elinchrom to appreciate its size and weight. The head weighs just 0.62 lb and measures 3.1 x 2.9" yet gives full-sized performance from any Quadra power pack. Small is also beautiful when working in tight spaces or hanging the head on a grid or boom. The exciting news is in the head's HS (Hi-Sync) designation, which means that it's optimized for use at high sync speeds as short as 1/8000 sec. to overpower the sun or use wider lens apertures. It's also a great benefit in stop-action photography. The Quadra HS has several dedicated, optional accessories but purchasing the Quadra reflector adapter gives you complete access to the full line of quality Elinchrom accessories and light shapers. The head comes with a head cable, reflector, multifunction cap and a Quadra protective cap. Small size, lightweight, and great performance make the Quadra system hard to beat.
