The Sony RX100's full-autofocus shutter lag (with the subject at a fixed distance) was only 0.153 second in Single-area AF mode. This increased slightly to 0.266 second in Multi-area AF mode. That's much faster than the average CSC, and competitive with many SLRs.

The one significant anomaly we found in our shutter lag tests was that the AF is very slow to lock on in continuous AF mode when the lens is set to its widest aperture: We measured very consistent lag times of ~1.2 seconds in that condition. Stopping down to f/4 reduced continuous-AF lag to the 0.314 second shown in the table above.
