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 is to allow 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.
The 4700's shutter lag was just slightly longer than average, at 0.9 seconds for full autofocus (average is probably about 0.8 seconds), dropping to a slightly better-than-average 0.19 seconds for shots in which the lens is prefocused by half-pressing the shutter button prior to the exposure itself. In manual focus mode, the shutter delay is about 0.42 seconds.
Cycle times at maximum resolution and quality are quite fast, about 1.5 seconds between the first and second shots, increasing to about 2.5 seconds for subsequent ones. Cycle times at minimum resolution and quality hover around 2 seconds, regardless of how many shots have been taken. (The internal buffer memory apparently comes into play for the first one or two high-resolution images.) Overall, this is a very fast shot-to-shot performance for a camera of this resolution. In Continuous mode, successive shots are captured every 0.24 to 0.25 seconds (Fuji's official spec is "about 0.2 seconds".) We measured the frame rate in movie mode at exactly 10 frames per second.
