Sony Cyber-shot DSC-HX50 review – Autofocus
One of the HX50’s most important features is its focusing speed. Sony says high-speed AF is capable of focusing at 0.1secs, and when using the vast zoom lens at it widest focal lengths the lens does indeed snap quickly into focus.
However, as the lens zooms, the focusing speed decreases, and at the maximum 30x zoom length the system can take around a second to focus, particularly in dim light. In very low light the AF assist beam does a good job of helping to find focus.
Overall, the AF speed is about what you would expect from a travel zoom camera with such a huge zoom lens.
