The Underrated Sequel to Nikon’s Most Famous Lens | Nikon 105mm f1.8

I was all set on the Nikon AIS 105mm f 2.5, not just because it’s Nikon’s most famous lens, but because of its one advantage for street photography, until I stumbled onto another 105 from Nikon’s archives.  The 105mm f1.8 AIS - released as a direct SEQUEL to the f2.5, almost a full stop brighter, supposedly without any optical compromises, yet compared to its predecessor a relative unknown.  Is Nikon’s sequel to their most famous lens overblown or underrated?
