Well that is the big thing with prime lenses in the 40-60mm range. Its hard to get a really bad one. You can find really bad 28mm lenses, or bad 85mm lenses, but around 50mm a premium price only gives a small advantage - which might even be irrelevant in some cases! Think about the Zeiss Otus, Sigma 50mm art, DA* 55mm, Sony Zeiss 55mm, and FA 50mm. The cost difference between these is huge, and while the optics are different, I would not say the FA 50mm is "bad" just because it is the most affordable
