I bought the manfrotto 303sph (secondhand-used), but one piece is missing. I made the connection like the photos. parts of the device come out in the photos I take. Can you help me with this?
Manfrotto is a dubious choice at the moment. Sell it and buy nodal ninja. If you do not want to sell, try shoot panorama. Perhaps because of the overlap frames there will be no problem.
I'm not sure about the nodal point. I bought a Sigma 8mm lens(new). I have got nodal ninja NN3. I take good photo to take better panorama: I got 303sph and sigma 8mm. Machine nikon d610
