I find some of my old lenses tend to underexpose so you might try changing your exposure from -.3 EV to like +.3 or .6 as a start, unless the background should have been a medium gray. Changing the ISO to 200 should also get a bit more shutter speed and cut down on the slight blur without adding significant noise.
1. Were you using a lens hood?
2. Double check all of the exposed lens filter surfaces for smudges, haze. be sure there was no condensation.
