Is there a difference between the black and silver Nikon 50mm f/1.8 E series lenses?

Question

The Nikon 50mm f/1.8 E-series has 2 versions: black (1979-1981) and silver (1981-1985)

Is there any difference between these 2 versions, apart from the color?

Answer 1

The later version has a chrome ring, but the differences are cosmetic - both are inexpensive, mostly plastic lenses, and optics are the same: 6 elements in 5 groups. They removed the chrome ring again when they released the AI-S version.

...the second update of the Series E 50mm f/1.8s finally being improved with some cosmetic in a more shiny finishes, aided with the reversal of decision of an aluminum lens mounting ring...
