The direct threaded coupling permitted by the Digital T-rings results in the most accurate and rigid attachment possible even with large and heavy cameras and videocameras. This system also allows the cameras lens to be located immediately above the large eyelens for eliminating the vignetting common in other systems (afocal projection).
