The SunwayFoto DDP-64M is a rotating head that allows you to pan at precise degree increments. This enables you to capture a series of photos at stop intervals that range from 5 Degree to 90 Degree that you'll later stitch into a panoramic masterpiece (possibly involving high-dynamic range capture as well). Remove and insert the attached key to easily change the detent (stop) interval. The DDP-64M features independent locks for the top platform and for the pan base. You can also use this indexing rotator as a traditional panning base. With a 22 lb load capacity, the DDP-64M supports most camera/lens combinations.
