Logitech today announced a Webcam specifically tailored to Macs. The Logitech QuickCam Vision Pro is a spitting image in terms of both specs and design of the PC-friendly I reviewed (and very much liked) last year, but Logitech sees fit to charge the few Webcam-less Mac owners out there an additional $30. The QuickCam Vision Pro will cost you $130 when it's released next month; the QuickCam Pro 9000 can be had for $100 or less.
Like its PC doppelganger, the QuickCam Vision Pro features a 2-megapixel sensor, a Carl Zeiss lens, and Logitech's RightLight technology, which I've found to work wonders in low light. Logitech states the camera can record video up to 1,600x1,200 resolution and deliver 30 frames per second when chatting on Skype or iChat.
