Since you've asked specifically about a 50mm I'll say my lowly Nikkor AF-D 50mm f/1.4 is every bit is good as the 50mm f/1.4 ZF Planar I ended up selling.

Save your money.
Geee... Do you think that's because they're the same design?
Guys, you're all talking about Planars and Sonnars... the Planar is a double Gauss type, and so is virtually every f:1.4 and f:2 50 - 58mm lens.

Sonnars? 105/2.5 Nikkor, the first version. The one which replaced it was a... double Gauss!
A well designed, well made dG will have the same look as any other well designed, well made dG. And so on.
Having handled a ZF lens once, (which was enough) I would buy one only to resell at a profit. The haptics suck badly.
