The Olympus has 5X optical zoom and uses a lithium ion battery.  

The Casio has a 3X optical zoom and also uses a lithium ion battery.  It shoots widescreen 848x480 videos.

Answer 2

Go with the olympus, theyre always the best kind of camera after nikon and canon.  Also it comes with a memory card and has image stabilzation. Thats great
