The S100 is the best of those you listed. Naturally it is the most expensive as well. It has a brighter lens and a slightly larger imaging sensor which nets higher quality images.
If you want a lot of cool toys to play with, the new Sony HX20V has every trick in the book. Cnet review the HX30V and gave it four stars; the HX20V is identical except for not having the built-in WiFi.
Hi all - looking to upgrade an outdated Canon SD450, to something newer (feature rich, great low light & outdoor photos, clarity, portable / vacation friendly, sub-$400); any thoughts on the below? or recommend something different?
(1) Canon PowerShot ELPH 520 HS
(2) Canon PowerShot ELPH 320 HS
(3) Canon PowerShot ELPH 110 HS
(4) Canon PowerShot S100
Thanks,
Jay
