The Cyclopital3D 25mm Wide Angle Adapter for Sony 3D Camcorders enables an expanded field-of-view on the Sony HDR-TD10 and HXRNX3D1U 3D camcorders. With the adapter attached and the camcorder's lens set to its widest focal length, users can achieve the 35mm equivalent of 25mm. The adapter also features 86mm filter thread, which allows users to attach additional filters (sold separately). The adapter attaches to the 1/4"-20 tripod mount on the bottom of the camcorder. A wide-angle lens hood and a lens cap are also included.
