Picture quality the same (excellent).
The A710 has more optical zoom (6X as opposed to 4X on the A570)
There is a slight penalty for more zoom.
Shutter lag will be a bit more.
(0.2 second for the A570 and 0.4 second for the A710)
Other than that.......toss a coin.
You can't lose.
Here is the comparison of specifications:
I Can't decide which model is better amongst Canon Powershot 570IS and Powershot A710IS.
I am surprised because both models are available at the same price. Can anyone suggest which model is good in technical aspects?
Thanks in advance
