If I read Strad correctly, he does not have the movable (i.e., variable) condenser. In that case, he would need individual condensers for the different lenses. I now have a D2V, the variable (movable) kind, but I started with just a D2. I had to change condensers when changing lenses (50, 80, 105, 135/150). Not a major pain, but it was inconvenient. Assuming you have the condensers in the first place.
