唔知BUY邊支好...
17-70os hsm
15-85is usm

If the quality of the non os sigma is the same as the os one, canon 1585 is much better!

我之前都係咁揀
最後入左15-85
我覺得佢個焦段好好用
日常生活好夠用

但唔代表s17-70唔好
佢個價位真係好抵

17-70os hsm --> 抵玩既多用途鏡, 可以去到2.8 (廣角時). 1:2.7既最大放大倍率, 平價既價錢
15-85is usm -->高質數既變焦鏡 , 15mm既廣角 (FF既24mm...), IS同USM都勁 價錢貴D...

其實相比其他SPEC......睇下你想唔想玩下MARCO....同埋有無原廠情結更好
