Do you mean is the A-80 much different than the A-70?

The A-80 has more megapixels (4.0) while the A-70 has 3.2 megapixels. With the A-80, you could record videos of up to three minutes with sound, and I believe with the A-70 you could record between 30 seconds - 1 minute with sound.

Here's some information/prices on the A-70
