I speculated earlier about a new sport, replacing the rifle with a camera in biathlon. Today I went skiing, and took mostly sharp photographs. It seems that with practise and concentration you can improve the sharpness of photographs quite a lot. On the other hand, I also used motion blur deliberately, shooting from the hip while skiing.
