Amy wants to get a new camera as a combination mother’s day/anniversary present. We already have the Nikon D50 for high end stuff, but it’s too big and bulky to carry around for candid snapshots of Ava. She wants something small that will fit in her purse or the diaper bag and that takes good photos. The only real requirement is that it uses SD memory cards and is available at Costco (thanks to their more-than-generous satisfaction guarantee). Any suggestions?
