Keith, I'm intrigued to know why you hate the Nikkor so much? I have it as my standard "walkaround" lens and generally I like it a lot - very sharp in the centre where it matters, light, compact, quick focus etc. Fairly hideous bokeh admittedly but you can't have everything.
About a year ago I had all three of the Nikkor, the Zeiss and the Voigtlander at the same time for my D700, and I sold the other two to keep the Nikkor - the Distagon is great optically but as the photos above show just absurdly big and heavy for an everyday lens - it's like having an 85mm on the camera all the time and I didn't like the balance of the camera with it on - obviously that may not matter so much for your gallery shoots.
I think the Voigtlander's a dark horse and well worth a go if you want an MF lens - it's tiny but very sharp, and has a less harsh look than the Nikon wide open. Plus if you want to use it on an FM3A it's way, way better ergonomically than the Zeiss - a really nice, compact package. The Zeiss seems to dwarf the camera with an FM3A and again I found the balance all wrong. A shame because it makes beautiful images.
