Hi, im deciding on 2 cameras. A Pentax optio W30 and a Olympus Stylus 720Sw. What i need to know from you guys is this. Do they both do underwater video/audio How does the 720sw do with close up "macro" mode shots. Like of bugs. I see it doesnt have a Macro mode, only Auto Focus. But im wondering if you just get close enough it it still takes crisp shots. If anyone has done this please post the results.
