In 2005, Quyen Le’s interest in videography and his knack for inventing led him to create an adapter to fit SLR lenses on a video camera. In sharing ideas with other DIY filmmakers, he quickly recognized the need for an affordable depth of field adapter. Although other DIY DOF adapters already existed in the indie filmmakers market at that time, Quyen was the first to introduce a DOF adapter with an upright image.
