I agree with the wrote - This adapter brings absolutely nothing, because the connecting plate (the small, yellow metal plate below) is smaller than the standard size. Therefore it floats into the receiving shoes HDR-PJ780 and PJ650 (normal size) and can not be fixed. For me this is the same problem. I have played around me then considers it, but I would of external display or lights that advise weigh something, because after a while the locking solves. If the adapter plate of the correct size, then it would be ideal.
