I'm looking to buy a digital camera for the imminent arrival of my\nfirst child. From my research, I like the Optio 555 for its zoom and\nmanual control (more important to me than the mom-to-be, who will only\never point and shoot) but am concerned about its speed. I also like\nthe Elph S400 for its (relatively fast) speed and ease of use.\nPicture quality is actually the most important feature to me, but I\nhaven't been able to find any head-to-head comparisons. I can't\ndecide which way to go - does anyone have any thoughts on which camera\nis better? Thoughts on other cameras would also be appreciated, but\nfrom my research, I'm really liking these two. Thanks.
