初看功能跟800 IS差最多的地方如下 ●7.1 Megapixels and 3.8x zoom 7百萬畫數(畫數夠用就好啦!XD) 光學變焦只有3.8 但因為廣角的關係 望遠端只有到105mm( 800 IS到140mm) 這就取決於廣角重要還是光學變焦重要啦!!!!!!! ●Wide angle 28mm lens with Optical Image Stabilizer 廣角廣角廣角廣角廣角廣角廣角廣角廣角廣角廣角廣角廣角廣角廣角廣角廣角廣角廣角廣角廣角 ●DIGIC III with Advanced Noise Reduction and Face Detection 請問新引擎跟舊引擎差在哪? (一般人可以感覺到嗎?還是只有規格上的提升?) ●AF/AE Safety Zoom for extra telephoto reach ●ISO 1600 感光到1600 (800 IS 只有800) 但是快門還是一樣只有15秒 Orz ●High resolution 2.5" LCD17 shooting modes including VGA movies (30 fps) with sound LCD 已經到 20萬畫數 (800 IS 17萬畫數) 動畫的功能強了一點 ●Range of optional accessories including Underwater Case
