Raid, since you say your 21mm won't work on the D700, I can recommend the 20mm f/3.5 Voigtlander lens. It is manual focus and chipped with a microprocessor so it will identify itself to the D700. It will also work fine on any film Nikons you have. AF Nikkors I use with my D700 are the 24mm f/2.8; 50mm f/1.4; 85mm f/1.8 D; 28-105 AF Zoom; and 17-35mm f/2.8 zoom. These all work very well, and it is nice to have some AF lenses. You can manually enter the ID of MF lenses into the D700 just like you can with the M9; but it's convenient, for the most-used lenses, to have AF (or at least Chipped) lenses that send this info to the camera automatically.
I've been using Nikons for almost 50 years, so I have accumulated a few lenses. Some manual focus ones I use with the D700 are the 15mm f/3.5; 18mm f/3.5; 35mm f/2 AIs; 135mm f/2.8 AIs; and the 180mm f/2.8. The latter is heavy, but is rock-solid in the hands for hand-held shooting. I also use, converted to Nikon F mount, the Leica 180mm f/3.4 APO-telyt (just one or the other on a given trip, never both). The long lenses snap in and out of focus so easily, I see no point in bothering with AF. But with the extreme wide angle lenses, AF can be helpful: It's pretty hard to see the difference in the finder between in- and out-of-focus. That might be an argument in favor of the 20/2.8 AF-D in place of the Voigtlander. Something I like about using extreme wide lenses on an SLR/DSLR rather than on the rangefinder, is that I can better see the three-dimensional depth perspective on the groundglass.
I haven't found a 35mm lens that I'm entirely happy with on the D700. The 35/2 AF-D wasn't very good. I sold it. The 35/2 Zeiss ZF.2 didn't handle well. I sold it, too. My best so far optically is the 17-35 Zoom Nikkor, but it's so heavy!
