Merry Christmas! Ok, I am a huge fan of Bokeh type photos and I was hoping that my new camera the NEX 3 by Sony could be adjusted to give me some of those awesome shots. I placed the camera in M mode and moved the settings to 0.5" and F5. I really wish that I could set the F stop a little lower but just couldn't find a way to do it. Overall, I was satisfied with the results.
To get those beautiful, blurry Christmas lights, use your lens with the lowest aperture. Place your subject as far away from the tree as possible and get as close to the subject as possible.
