The small Adapter from walimex is one of the big ones! Because only with this item it is possible to mount cameras and heads, which are equipped with 3/8 inch thread, on a tripod with 1/4 inch screw. In order to achieve a higher stability, the Adapter was modified with some additional windings.
With this set you will get even five of these convenient, small helpers. As price-conscious photographer you will surely like it!
