Re-post December 2011
The one thing I really enjoy about my Leica M9 is the ability to shoot without a flash in low light. This is only possible because I can shoot at very low apertures (i.e. f/1.4 or f/2.0). The only down side with the Leica M9 is its poor high ISO if shooting in color.
This picture of my nephew was taken only with light from a few lanterns and street lights.
