Sony stops shipping ‘X-ray vision’ camera
Yes it can see through clothes, no it was an accident, honest

A year ago -- Sony says it has halted shipments of a video camera that can see through clothes, and no, this does not appear to be a publicity stunt. Just shy of a million of these - now intensely valuable - units have gone out of the door, but Sony, which says it knew nothing of the interesting application of its camera until magazines tipped it off, has modified the feature so it only does what it was supposed to do. The Handycam uses infrared to allow shots to be made in darkness, but apparently if you use it in daylight or a lighted room with a special filter it can see through clothes, especially thin ones and swimsuits. Sony is hard-wiring the camera so it only works in the dark, but if you're lying on the beach and you see somebody filming you intensely, worry.
