想問下大家有冇用過以下兩支鏡頭?邊支會好d呢?
1.Canon EF 24-105mm f4.0L IS USM
2.Sigma 24-70mm F2.8 EX DG HSM
不計L鏡之名氣，只計實用程度、相片質素和性價比。

如果全開 f2,8 成像得的話

一定揀 24-70mm f2,8

如果要下下收到 f4,0 先用得下就................

I have the old sigma 24-70/f2.8 for Nikon, on D200 its photos are sharp, but 2.8 is not that good, very soft. I don't know how good the new version Sigma is but my 2 copies of 24-105IS are very sharp at f4 @5d2
