Thanks to Paul and Altaf,but I am a little confused about sharpness now,I thought I can use a slow shutter to capture and emphasize the focus,when the focus is moving.I will consider your comments carefully.Vivien

The sharpness of a lens is controlled by the design and the quality of the elements use to make up that particular lens.
The sharpness of a photograph is determined by many factors:
Aperture affects sharpness but it is not the primary reason why images appear unsharp. A lens usually has a sweet spot near F8 (assuming you are shooting 35mm) using aperture values of f22 and higher tend to approach the diffraction limit of that lens, thus images begin to appear unsharp. The shutter speed, proper focus, and the stablitiy of the camera platform generally control sharpness of a particular photograph.

Quick comment to Vivien, slower shutter doesn't control the sharpness of a photo. Aperature is what controls the sharpness and DOF.

Thank you for the comments. The reason I shot this image at 1-1000 is to stop the action. The part that makes the shot click for me is the sign in the background. I don't know, I really try to look for things that are going to make the picture have a little extra. What do you think?

Wonderful moment!I think maybe it will be better to use shutter slower than 1-1000,slow shutter makes good effect on focus.IMHO.

Wonderful capture of the action, nice sharp focus, good exposure. Too bad there are so many distracting elements in the background.
