G9和G7作比較的話，
G9有哪些明顯機身效能上的提升？(撇開LCD變大、畫素提升....這些比較花俏的功能)
像高ISO的雜訊、機身對焦速度、人像對焦、電力持久度、操作介面的改善........這些方面有無提升呢？謝謝
簡單整理dpreview的說法,
http://www.dpreview.com/reviews/canong9/
高ISO的雜訊G7表現較佳..
G7 actually produces better results at ISO 800 and above
機身對焦速度G9較佳..但could be better
G7
Half-press Lag (0->S1) Wide angle (AiAF or FlexiZone focus) ~ 0.45
Half-press Lag (0->S1) Telephoto (AiAF or FlexiZone focus) ~ 0.6
G9
Half-press Lag (0->S1) Wide angle (AiAF or FlexiZone focus) ~ 0.4
Half-press Lag (0->S1) Telephoto (AiAF or FlexiZone focus) ~ 0.5
電力持久度G9較佳..但Battery life not great
G9 240
G7 220
在dcresource也說Below average battery life
