I’VE BEEN WRITING ABOUT NEW DIGITAL CAMERAS, but there’s something to be said for surfing the backside of the technological wave: Sony’s former top-of-the-line camera, the DSC-F717, is now selling in the neighborhood of $600. (Yesterday it was $499 when I got the Amazon recommendation — now the price is back up for some reason.) It’ll probably continue to get cheaper, and its predecessor, the DSC-F707, is available for $400. It’s certainly capable of producing some amazing photos.

I wish that everything got better and cheaper as fast as electronic gadgets do.
