Conclusion:
I'm leaning toward getting the Sigma 30mm 1.4 for street photography/portrait, the Sony 50mm or Sigma 60mm for portrait photography, and Sony 18-105mm for everything else.
Note that the sigma lenses do not have image stabilization. The sigma 30mm 1.4 is similar in size to Sony 55mm. The Sony 18-105mm has internal zoom, meaning that it doesn't protrude.
