Autofocus Systems: Speed, Accuracy, and Tracking

Precise focusing remains a cornerstone for any camera, especially for genres such as wildlife, sports, or portraiture where critical focus on eyes is vital.

• Pentax Q10 autofocus: Features a contrast-detection AF system with 25 selectable points and face detection. Continuous AF and tracking are available but rely on slower contrast detection, limiting performance in fast or erratically moving subjects. No phase detection exists on the sensor or otherwise.

• Sony A200 autofocus: Employs traditional phase-detection AF with 9 points, including the central point sensitive for low-light focusing. However, it lacks face or eye detection, and continuous autofocus tracking is absent. Phase detection allows quick and accurate focus locking but struggles with continuous tracking in unpredictable motion.

The Pentax’s 5 fps burst shooting outpaces the Sony’s 3 fps, but practical focus acquisition before burst shooting favors the Sony’s phase focus, particularly in static or controlled movement.

Autofocus verdict: For fast action and moving subjects, the A200’s phase AF provides a more reliable lock-on despite fewer points. For simple portraiture or street use with stationary or slow-moving subjects, the Pentax’s face detection adds ease, though slower responsiveness can be a limiting factor.
