Cameras are not always compatible with all tripods on the market as they can have different thread sizes. Though most cameras tend to possess a 1/4” (6.4mm A thread), some tripods only possess a 3/8” (9.5mm B thread) and visa versa, making them incompatible with each other.  This Hama Thread Assortment for Camera Tripods kit provides you with a simple solution.
