Christmas Light Bokeh

This was a real treat to shoot and to have it turn out right. My sister in law had some light fixtures hanging over her dinning room table that had these pretty pieces of crystal suspended underneath them. They were at a perfect height for me to catch the Christmas tree lights in the background. This was taken at 1/20 of a second, ƒ5.6, ISO 800 with the 55 - 250 mm lens. For some reason the 18 - 55mm lens was having trouble auto focusing this night.
