In April 2005, Apple released a firmware update for the iSight to improve audio performance.

As of October 13, 2008, the external iSight was no longer for sale in the Apple online store or in retail locations.

The external iSight's ¼-inch color CCD sensor has 640×480-pixel VGA resolution, with a custom-designed three-part F/2.8 lens with two aspherical elements.

It features autoexposure, autofocusing from 50 mm to infinity, and video capture at 30 frames per second in 24-bit color with a variety of shutter speeds.

The actual camera only takes up one-quarter of the unit; the remaining space is primarily occupied by its two microphones and mounting socket.

The FaceTime HD cameras included with the 2011 and later models of the MacBook Pro and iMac can output 720p high-definition video.
