Shutter Lag / Cycle Times
When you press the shutter release on a camera, there's usually a lag time before the shutter actually fires. This time allows the autofocus and autoexposure mechanisms time to do their work and can amount to a fairly long delay in some situations. Since this number is almost never reported on, and can significantly affect the picture taking experience, we now routinely measure it using a custom electronic test system.

Very fast: Captures up to 4 shots, then you have to wait for the memory buffer to clear. |
The FinePix 4900 starts up surprisingly quickly for a camera with a telescoping lens, and its cycle time is pretty fast as well. Our only complaint about its speed is the somewhat longer than average shutter lag time in full autofocus mode. In continuous mode, the 4 frame per second performance for four frames is impressive, great for capturing exactly the right moment in fast-paced action photography.
