DXOMark went through some of their reviews to determine what the best lenses for the Sony a7RII are at the moment. Their pick for the best standard prime is the Sony FE Carl Zeiss Sonnar T* 55mm f/1.8 ZA, best portrait lens Sony FE 85mm f/1.4 GM, and best land scape Carl Zeiss Batis 25mm f2. I would really like to see where lenses like the popular Zeiss Batis 18mm and the Sony Planar T* FE 50mm f/1.4 ZA fall.
