I haven't tried the 1.8G but I specifically tested the 1.4G for astrophotography. I found it to be not quite suitable for that purpose at 1.4 (check out the blue halos on the mercury lamps too):

85mm f/1.4 AFS-G at f/1.4. Really good for a 1.4 but those aren't pinpoints.

but it's much better by f/4.0, and I consider it to be excellent for a 1.4 design:

85mm f/1.4 AFS-G at f/4.0

Holy Yikes, Batman! Thanks, Tony, for doing the test. That first one doesn't look good.

However, I did tests myself and the lights were pretty round (not perfect though). The magenta cast was removable in ViewNX2 that I use.
