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 using a proprietary Imaging Resource test setup. The chart below
shows the results of our timing tests on the Coolpix 775.

|
|
| Power On -> First shot |
|
About average for cameras with telescoping lenses. |
| Shutdown |
|
Faster than average. |
| Play to Record, first shot |
|
Time until first shot is captured, from "Instant Review" mode. About average. |
| Record to play (max/min res) |
|
A bit faster than average. |
| Shutter lag, full autofocus |
0.81 Wide |
Faster than average among similarly-priced cameras. |
| Shutter lag, prefocus |
|
A bit faster than average. |
| Cycle Time, max/min resolution |
|
Faster than average. Max res gives this speed for 5 shots, then about 5-8 seconds per shot. Min res lets you shoot this fast for a large number of shots. |
| Cycle time, continuous mode |
|
Quite fast, but a lot of variation in cycle times from one frame to the next. |
Overall, the Coolpix 775 looks like a fairly fast camera. Autofocus delay is lower than average, particularly when the lens is zoomed to its telephoto position. (The autofocus of most cameras slows markedly as the lens is moved toward the telephoto setting.) Shot to shot cycle times are fairly fast, and a generously-sized buffer memory lets you take five pictures without pausing, even in the highest resolution/quality mode. Overall, a good performance.
