For macro, get a proper Apo Macro lens, probably around 120mm. It will cost you though, and a lot. There's a recent thread on macro on the LFPF forum. Consider also using (reversed) enlarger lenses if a shutter is not necessary for your purposes.
For a longer portrait lens, consider:
- a 210mm is not really long enough for me, though they tend to be fairly small and light and you can get good magnification even with shortish bellows
- a 240mm plasmat (e.g. Symmar-S) is huge+heavy in a Copal #3. Needs more bellows.
- a telephoto lens will be small, light and not need much bellows, but it will be quite slow (f/9?)
