Why SmallRig do it？
"For a considerable duration, the photo and video industry has been characterized by diversity but lacks standardization, resulting in poor user experiences. According to surveys, over 70% of users encounter compatibility issues when utilizing diverse shooting equipment. Moreover, more than 30% of users have expressed a demand for a professional and standardized information source within the market, as the absence of such a resource has substantially inflated the cost of equipment compatibility. In response, we are introducing industry-wide standardized design specifications for photo equipment. Our objective is to advocate for industry standardization to streamline user decision-making processes and reduce associated costs."
