With Olympus’s 7-megapixel models, the Olympus SP-320 and the Olympus SP-310, the company caters to that snapshooter who wants a camera with more manual options than are offered by entry-level point-and-shoot models.
The only difference between the two is the digital image stabilization available on the Olympus SP-320. That mode simply uses a higher ISO sensitivity setting in order to use a faster shutter speed.
