Small shot

Exilim Zoom: The advent of compact point-and-shoot cameras has lightened loads for photo buffs, and Casio’s new credit-card-size digital camera is another big step in the trend toward smaller. Measuring 3.4 by 2.24 inches and less than an inch thick, this high-resolution, 4-megapixel camera slips into a pocket or purse. It includes a slew of features: a 2-inch monitor, a 3X optical zoom lens, a built-in speaker for up to 40 minutes of voice recordings, up to 90 minutes of continuous shooting on one charge of the lithium ion battery, 10 MB of built-in-flash memory, a built-in flash with red-eye reduction, a self-timer so the shooter can get into the shot, and a separate cradle for charging the camera and automatic transfer of images to a computer. All this in less than a pound.

Casio Exilim Zoom EX-Z4U lists for about $400; slimmer non-zoom EX-S3, $350. (800) 706-2534, www.casio.com.

Ocean Aqua Frame: Bored with photo frames that just sit there? The Ocean Aqua Frame gets into the act with three colorful fake fish that swim around in water sandwiched between two panes of glass with the help of hidden magnets that keep the fish moving. Turn on a little switch, and a recording of ocean sounds completes the mood. The frame accommodates a 4-by-6-inch photo behind the glass, making the photo subjects look as if they’re underwater.
