My recommendations:
50mm, 80mm, 150mm*, 250mm lenses, all CF or later
50mm, 100mm, 150mm*, 250mm lenses, all CF or later

If you do not need the electronic interface, the CF is the best buy for multicoated lenses, easier to get serviced, all use the same size filters [B60], easier to use than the C lenses and newer than the C lenses. CF lenses are lower cost than the later lenses, but worth the difference in cost above the C lenses.

I have CF 38mm [SWC], CF 50mm, CF 80mm, CF 150mm, CF 250mm and a 2X extender

* 150mm or 180mm only if you shoot portraits
