Part of me thinks the 7million pixels is overkill but part of me likes the 6x optical zoom in the Ixus 700. But then again, the Ixus 500 is tried and tested and looks like a fantastic camera whereas the 700 isn't as tested.

I've also read there can be problems fitting a 6x zoom into such a small camera and it can compromise the image quality even if not utilised. Any truth?

(Pixmania have the Ixus 500 for £240 and the Ixus 700 at £298)

What to do?

Edit: Price isn't really an issue since I have plenty of SD cards that the 700 uses. If I got the 500 I'd have to get a memory card so it kind of offsets the price.
