Take off the polarizer and shoot another roll with the 50/1.4. Use all apertures too. And don't expect a 1960's-vintage lens to be tack-sharp at F1.4. All fast, normal lenses from that era will show some spherical aberration, coma, etc, when shot wide-open. Not that that's always a bad thing. The "soft" look can make for some nice portraits.
Yes, the pre AI 50/1.4 Nikkor-S wasn't very sharp at 1.4.
