Shutter

Higher shutter speeds make it easier to capture fast-paced action, ensuring that you never miss the perfect shot.
Autofocus
The Pentax K-S1 includes two autofocus (AF) systems: contrast detection and phase detection, with 11 number of focus points.
While contrast detection is generally more accurate and precise, phase detection autofocus is faster and more effective in most situations, particularly when photographing moving subjects.
Phase detection autofocus works by dividing the incoming light into pairs and then analyzing how they intersect on the camera's sensor. This method allows the camera to determine not only if a subject is in focus but also the direction and distance needed to adjust the focus to achieve perfect sharpness.
On the other hand, contrast detection autofocus works by analyzing the contrast of an image and adjusting the focus until the highest contrast is detected. While this method is very accurate, it can be slow, especially in low light conditions or when photographing moving subjects.
