For the last week or so, I have been really "under the weather," sick with stomach problems+. It was not enough to go to the hospital sick, but close enough. I'm beginning to get better. However, I have not been able to really test the new X1 or the Sigma 50mm Macro. If there are any issues with them, Leica or Sigma will have to resolve them, but I do not think it is even a remote possibility.
I am very happy with the direction I took with my equipment, but will explain better in the future. Right now, back to bed :)
