  1. Are the front and back elements of the lens perfectly clean, free of fingerprints and oils?
  2. Did you use any type of filters like UV protection etc?
  3. Did you go to e.g. Flickr and research this lens for pictures taken into bright light sources and do they eventually exhibit rth same phenomena?
  4. Is your sensor clean which I don't think is the issue but better ask?
