The 8-element Zeiss ZF 50/2 and the 5-element Micro-Nikkor 55/3.5 seem to be at the opposite ends of the flare-prone spectrum within the world of 50/55 macros, I reckon.
An early multi-coated 55/3.5 was my first Nikkor lens in 1975. I used to marvel at it's lack of flare, especially compared to my other lens, a Vivitar T-4 28mm/2.8.
