If you are of a certain age, you can date your vacation photos by camera-friendly technology at the time. Polaroid and Kodak Instamatic cameras are relics of a bygone era. In fact, more photos today are taken with cellphones than with traditional point-and-shoot cameras. High-quality images are sacrificed for convenience and immediate gratification on photo-sharing sites. But with the new Sony Cyber-shot DSC-RX100, you have a small, fits-in-your-pocket, zoom camera that’s packed with amazing features: one-inch sensor, which means higher resolution and sharper images; 3.6X Carl Zeiss lens; auto-cropping; and a burst mode that can fire off 10 frames per second. The camera charges itself when connected to a USB port or wall outlet. David Pogue, who reviews gadgetry and technology for the New York Times, says this about the RX-100: “No photos this good have ever come from a camera this small. You’ll appreciate that the RX100 has single-handedly smashed the rule that said, ‘You need a big camera for pro-quality photos.’ To prove his point, he created a personal and quite dazzling slide show of photo samples using the Sony RX100. $650.
