If you found them on the website, then you can check mark three of them at a time and hit compare. If you look at the specs then you will see the difference.
Canon lists NINE Digital ELPH Cameras on their website, including three new models: SD890, SD790 and SD770.
Maybe I'm missing something, but I'm having a tough time figuring out the differences between their models (does the numbering system mean anything?) Yes, I do see that some have 7.4 and some 10.3 megapixels, but besides that.
For example, the SD750 and the SD1000 seem to have basically the same features. Can anyone give me a primer on Canon's Elph models? Thanks!
