Autofocus (AF) speed and accuracy directly influence a camera's suitability across photography styles, especially fast-paced scenes like wildlife or sports.

The SZ-15’s AF system is contrast-detection based, offering single, continuous, and tracking modes, with face detection capabilities but no animal eye AF or phase detection. The number of focus points is unspecified but known to be limited in small sensor compacts. Practical testing reveals the SZ-15’s AF to be moderately responsive at wide angles but noticeably slower and hunt-prone when zoomed extensively.

The FX700 also relies on contrast-detection AF but omits face detection and continuous tracking, focusing more on simple point-and-shoot precision with single AF. Its Venus Engine aids in faster focusing compared to older compacts; however, it lacks AF tracking for moving subjects, which may frustrate sports or wildlife shooters.

Manual focus is available on both, though neither offers advanced focus peaking or magnified live view aids - a shortfall for macro or critical focus applications.

Regarding exposure, both cameras support manual, aperture priority, and shutter priority modes, catering to enthusiasts who desire creative control beyond full automation. Exposure compensation is also present on both, ensuring adjustment latitude in varied lighting.

To summarize, for photographers requiring swift autofocus tracking in action photography, neither camera excels, but the SZ-15’s face detection and continuous modes provide a modest advantage. The FX700, with simpler AF modes, better suits static subjects or casual shooting.
