I just wanted to say: regarding this Summicron and Nikkor test, that I did have a lens hood for my Nikkor lens, but my friend did not have one for the Leica lens. So we felt it only fair to shoot the pics without the Nikon hood. I've always used lens hoods for my lenses, as it really does make a difference in the pics most of the time. I also try to use metal screw on hoods, as they have the added bonus of protecting the front of the lens from impact dings.
