What is a fast shutter speed?
A value around 1/250s or below can be considered fast. When we say 1/250s, it means one-hundred-and-two-fiftieth of a second. Similarly, a shutter speed of 1/500s implies that the shutter stays open for one-five-hundredth of a second. 1/500s is faster than 1/250s.
Is focus point important?

Do professional photographers use autofocus?
For most of the twentieth century, manual focusing was the only method of focusing a camera until autofocus became a standard feature of more modern cameras in the 1980’s. Most professional photographers continue to forego using an autofocus system because manual focusing allows them maximum control over their images.
How does focus work in a camera?
To allow your image to be sharp, or to allow you to intentionally not focus, the camera and lens work together to change the distance of the lens from the sensor or film in order to control where the captured light converges. When the light converges precisely at the plane of the film or sensor, the image is in focus.
