First a word about flash.....

After a flash, it takes a period of time to recharge the capacitor that fires the flash.

That time is affected by how fresh the battery is, and how far away the subject is.


Regarding shot-to-shot time:
I don't know of any database that has this information in a format that will let you easily compare many cameras.

However, the information is available.
If you want to spend the time, here is where to find it.

Go to the reviews at Steve'e Digicams:

Go to the review of the camera that you are interested in. Then go the the page titled ''Steves Conclusions''.

There you will find a paragraph that talks about performance. In that paragraphy you will find information about shot-to-shot, burst, and continuous timings.
