I have the L-shaped quick-release plate for the Canon 40D bought them together with the sliding plate (nodal point) to be able to use in the panoramic photography (portrait). One advance, materials and workmanship are ok. However, the vertical leg is where the camera is fixed not long enough or the slot in the mounting bolt for the camera is running short. You can not attach to the leg so the camera so that the sockets are freely accessible to the remote trigger or timer and directed upwards. If you want to connect or even flash timer on the camera, the camera can be precisely placed at the angle. I have set a photo to.
