Clay, I'm with you, if it were me I would sell the zoom and go for the primes. But do you have something else to use while waiting for Photokina ?
I keep my fingers crossed that we will see some new fast AFS Nikkor primes at Photokina, like 85mm AFS (VR?), or 50mm AFS, or 28mm AFS. Hopefully all of them. I deliberately do not specify any fastest aperture wishes because I really do not care that much as long as they perform excellent wide open. I think that with the ongoing high ISO development it becomes a bit less important with the ultra, ultra fast apertures. I would rather have high quality than high speed.
Maybe all this is just wishful thinking, but if that happened, could you then wait buying new primes until something like january 2009 ?
