Autofocus Systems: Speed, Accuracy, and Usability

Autofocus performance is a pivotal factor, especially for wildlife, sports, and fast-paced street shooting.

Pentax X-5

The X-5 relies on a relatively basic 9-point contrast-detection AF system. While it can track moving subjects moderately well at its continuous shooting speed of 10 fps, the lack of continuous autofocus during bursts limits its efficacy for fast action. Face detection works adequately, but the system struggles under low-light or low-contrast conditions typical of indoor or wildlife environments.

Samsung NX3000

The NX3000 improves significantly with 35 focus points including a selectable center point and face detection. Its system supports continuous autofocus for tracking moving subjects, an asset in sports and candid photography. Contrast detection remains slower than phase detection systems but is faster and more reliable than the X-5’s setup.

AF accuracy and speed improve with quality NX-mount lenses that perform well even in lower lighting.
