Metabones recently updated their Canon EF to Sony E-Mount Smart Adapter IV to Metabones T Smart Adapter IV ($399) with improved anti-reflective internal coatings. According to Metabones’ website, “Enhancement on new MARK IV (MB_EF-E-BT4) vs. old MARK IV (MB_EF-E-BM4): The inner hole is painted with flocking material coating. This can further reduce the internal reflection.”
