One of the highlights at PMA 2007, the Photo Marketing Association's annual tradeshow, was the Sony Cyber-shot DSC-G1 digital camera. A wireless digicam is by no means a new invention (Canon, Kodak, and Nikon have been shipping them since 2005), but it's suprisingly a first for Sony.

Available next month for a whopping $600, the 6-megapixel G1 has a large 3.5-inch LCD, 3x optical zoom, impressive 2GB of internal memory (expandable with Memory Stick Duo and PRO Duo cards), slide show with music capabilities, and a bevy of wireless sharing options.

The camera-to-camera feature enables up to four cameras to wirelessly send photos to one another (as long as those photos aren't copyright-protected, of course), and users can even upload images directly to a DLNA-enabled computer for instant uploading to the Internet.
