if u shoot someone near, say within 1-2 meters, with flash, confirm overexposed.
otherwise, for general usage, not bad as u can see from above photos.
Had a chance to use it underwater this weekend, not bad also. Not sure about olympus and optio. U can ask around the other 2 sub-forums for feedback.
But since Z33 cost only around $300, cannot hiam so much lor. Shutter, playback and zoom response all agonisingly slow.
