I know your message is directed to digitalxd1, but let me 'kaypoh' a bit.
I have been using manual focus camera bodies and lenses for more than 20 years, and reluctantly switched to a AF body (a Nikon F4) in 1993. After making the switch, I found that shoot with AF was such a god-blessed convenience especially when grabbing quick 'moments'. Keep in mind that the AF system in the F4 was not great. After so many years of shooting with a manual body, I could still 'lock-onto' my subjects faster than the camera.
After the F4 (I still have it), I downgraded to a Nikon F100. The AF system was faster than the F4. And again, I enjoyed the convenience of AF, but I could still manual focus faster than the camera. I do not own a Nikon D3, but I have handled one in the past. Its AF was not a great deal faster than the F100, unless using AF-S lenses.
Bottomline is, AF is good to have if you need it, especially if you shoot events such as kid's birthday party, wedding and AD&D. You can still do manual focus with the Nikon 85mm f1.4 AF-D. BUT the image quality from the Carl Zeiss lenses simply cannot be rivaled.
You may argue that fact that Carl Zeiss-like image quality can be achieved through digital enhancement such as Curve Adjustment and Unsharp Masking. To be very frank, I have been using Adobe Photoshop since version 2.5 and I can comment confidently that no amount of Photoshopping can reach the same level as what Carl Zeiss lenses can achieve, especially the near-perfect bokeh and impeccable skin tone gradation.
If you have the chance to compare a pro-grade Nikon lens with a Carl Zeiss ZF lens, try to photograph a human subject. The first difference you will notice is the skin tone. The skin colors from a Nikon look burnt and the texture look coarse. The Carl Zeiss will present a natural and livelier skin colors. The texture is soft and fine, yet sharp. The contrast is very neutral. Depending on your purposes, I will recommend you to buy the Nikon if you are an event photographer. If not, then go for the Carl Zeiss and enjoy it. I can assure you will not regret your decision.
About having giddiness, you 'may' encounter it at first, but give yourself some time to get use to the lens. Just like a new pair of spectacles. The more frequent you wear it, the more comfortable it becomes, and the initial giddiness will disappear.
