How to set the shutter and aperture when the sports meeting wants to take photos of athletes with large depth of field when running?

In your question, the words are reversed.

Prominent figures, blurred background, depth of scenery, not too big.

If you want to shoot a blurred background, you must use a SLR camera and a telephoto lens.

To produce a shallow depth of field effect with a blurred background, there are several elements:

1. The photosensitive element should have a large area.

The focal length of the lens should be very long.

3. The shooting aperture should be large

4. The shooting distance should be very close

5. The foreground and background should be separated by enough distance.

The photosensitive element of ordinary digital camera is too small and the focal length is not long, so it is almost impossible to obtain obvious blur effect.

Even for telephoto DC, blur is not enough.

Under the condition of SLR+telephoto lens, if you want to blur obviously, you need to use a large aperture+high-speed shutter as much as possible, and shoot closer to make the distance difference between the foreground and the background as wide as possible.
