The Voigt is neither rare nor expensive. And is as good or better than anything Nikon currently makes. It might have a tough time running against a Noctilux, but then you're into esoterica, not a current production lens. That is less than $400.

But if I had Noctilux kind of money I'd be shooting Leica and be done with it...

My point is that you made a sweeping statement ("worst thing you can do is buy some aftermarket lens"). I provided a counterpoint because I find it to be an overgeneralization. You also made a pronouncement about the reason behind IS implementation and I disagreed and provided alternative (and widely accepted) reasons for the current respective technologies.

Zeiss and Voigtlander are aftermarket lenses, and will blow much of the current Nikon lineup out of the water wrt IQ. Features and other performance factors are another matter, but that is all part of the problem - there are no clear cut answers, and everything is a compromise.
