Canon ixus850 & Canon ixus900，點揀好？

900 Ti 係冇防震, Ti 係解 Titanium, 個機身係鈦金屬, 硬淨啲, 有千萬像素。
要有防震就 850 IS ,係光學防震, 但係得710萬像素。
兩部機都有 Face Detection.
850 IS 平 900 Ti HK$200。
其實响Compact DC嚟講, 千萬像素真係冇セ嘢意思,因為用得 Compact DC 影相都係貪方便易用,影一幅千萬像素嘅相,儲存時間長,又食Memory,卡都要預多啲大啲,有幾何會將張相放到A1紙咁大?伍佰萬像素嘅相,自已印A4嘅Photo紙己經靚到不得了,慳二佰蚊買多張卡,狂影乜都得。
兩部機都係影人像好,影貓、影狗就唔掂,重有影風景都唔係太好,因為四角有黑角,但係 Compact DC 係專為影一般家庭、人影而設,所以兩部機都OK啦。
但係我個人就會揀 850is,過兩日就去買。

I like 850 as it has wider angle and vibration reduction.
