What terminology is used to describe how quickly a digital camera takes the picture after you press the button.
What is range of timing?
What is typical timing? It's called "Shutter Lag."
Here's a link showing a chart of various cameras and their shutter lag as well as the time it takes to shoot five frames. You will not see any DSLR's listed, because they have no shutter lag. If you click on the column heading, such as "One Shot," the chart will sort according to that measurement.

Here's a list of five good cameras with brief shot-to-shot delays of less than 1.5 seconds (in good light) each: http://www.cnet.com.au/digitalcameras/ca...
Canon Powershots SD850-IS and SD750, Sony Cybershots DSC-T100 and DSC-W55, Kodak Easyshare C875.
If you pre-focus by pressing the shutter button half-way down while aiming at your subject - or where you anticipate your subject will be when you want to take the picture - it will help considerably. You can set your camera in "Sport" mode or "Scenery" and this will minimize the lag. If you do not use the flash, it will help. If you turn off "face detection," it will help. If you turn off the LCD monitor and use the viewfinder only, it will help. If you use the continuous shooting mode for a burst of 4 or 5 shots, there will be no pre-focus in between those shots. For most point and shoot cameras, this will give you 1.5-to-2 frames per second, but you can't use flash.
Some point and shoot cameras are better than others. I have a Canon Powershot SD900 that seems quite fast to me. If you go to http://www.dpreview.com and read the reviews (once they are available for the cameras you are considering), you can go to the page called "Performance" and see exactly what the tested shutter lag is, as well as several other performace benchmarks. shutter latency There's a number of terms you might hear:
Shutter delay
Shutter lag
latency
Timings are typically in the order of milliseconds, a second divided into 1000 parts. So 500 milliseconds is half a second, 750 milliseconds is 3/4 of a second, etc.
There is no "typical timing". It will vary from camera to camera, even within the same model, as the firmware (software built-into the camera) can change and improve camera response.
Even digital SLRs have shutter lag, from the need to have the mirror flip out of the way. For example, the D200 has a shutter lag of 50 milliseconds (that's very fast!) or 0.050 seconds.
Point and shoot cameras vary in response. A few years ago with point and shoot digitals, it was normal to actually take a second or two for the system to lock focus, determine exposure and then take the photo. Now, many point and shoots can respond with little to no perceptible delay.
The chart from the UK in the other response...not clear how they determined the shutter lag, since it appears to include time to start recording. But it's a good start. The only way I know of to actually test shutter lag is to photograph a digital clock, triggered to start the same moment the shutter release is tripped. The clock will display the amount of elapsed time from the moment the shutter was release to the moment the image was actually captured. go to howstuffworks.com
to find out your answer you have shutter speed
you have a processor
you have your card
the speed of the camera is related to the speed of the above.its how long it takes to process/record image to card.
mys3pro fuji will take aprox 9 photos /minute
hope this helps |
