The 3/8 "female thread of the tripod head (not the 1/4" from the hot shoe foot-thing) is unfortunately offset well 4mm inward. It grabs until very late! In my tripod it packs even not at all, since this is the thread although 5mm long, but also begins to 1mm. Thus, it is not possible to mount the ball head purchased on the tripod.
From my perspective, I would argue that there is either a lack of production, or intentionally, so that the Blitzschuh- Holder fits better.
