And if you don’t take it apart into pros and cons, then here’s what I’ll say: It can be used for macro, since it works more or less adequately near and af and is sharp on a covered one. Who and how they take portraits, I can not understand. At a distance of 5 meters, either manual focus, or contrast af in live view. In general, optically it suited me, but mechanically it didn't. It's better to buy cheap manual glass. Better take the Yongnuo 50mm f/1.8, it can be optically worse (although it's better open), but it's even cheaper and the assembly seems to be even better. In addition, the diaphragm is rounder
