I can't say I've actually seen anything about it, but I've always assumed it just reads from a smaller portion of the CCD - rather like zooming in on a paintbox programme. I presume that the resolution suffers when you do this!. I also presume the anti-jitter works in the same way, as the image moves about the CCD, move the scanned 'window' to follow it. BTW, the digital zoom is used in conjunction with the normal focal length zoom, it only comes into play at the higher zoom settings - thus giving a much higher zoom range. -- Nigel. /--------------------------------------------------------------\ | Nigel Goodwin | Internet : nigelg@lpilsley.demon.co.uk | | Lower Pilsley | Web Page : http://www.lpilsley.demon.co.uk | | Chesterfield | Official site for Shin Ki Ju Jitsu | | England | | \--------------------------------------------------------------/
