You cannot compare this lens with the modern 50mm lens with million pieces of glasses having aspherical surfaces and special low dispersal materials.  This lens has its own character and this lens had been sold for more than 20 years (with two different versions but have the same optical formula).  There is no prefect lens in the world but we should know their characteristics and make use of them.
Pentax 50mm f/1.2 is a lens for night. Even in a very strong back-lighting situation the lens is still having a very good performance.
