各位師兄
小弟想買鏡，哪一支是比較好呢？是17-55 f/2.8 好，定係24-105 f/4L好

唔使諗，我兩支都用過，aps-c既話，畫質17-55 is 贏晒。
17-55絕對係L鏡既級數。

我就會買24-105，因為我現在用緊，我當它是天涯鏡用，不過我本身是用5D mark II ，而且又有支小白IS.....所以我會比我我會買24-105....因日後FF機仍用得...

[henrynghc]

一定係17-55
24-105真係上FF先買!
淨係17 wide 同2.8 光圈贏晒

現用500D +17-55+70-200 4L is+Sigma 50.4
如真上FF(機會好微)--賣17-55
買16-35 2.8+24-70 2.8

[溫神]

請敎 500D + 17-55 f2.8 好定 17-40 f4L 好?

[sannaso]

17-55 2.8 is usm la!no need to think!

[sannaso]

for my 7d is prefect!!

[KAILAP]

講真，先唔好論佢既工能(is+usm+2.8,只有小白is同百微先可以有晒呢3樣)，佢影出黎既相同用ff機+L鏡真係差唔多，24-105L唔係唔好，不過用係aps-c到會發揮唔到。
同埋2.8同4既光圈真係差好遠。正好多同埋增加你係夜晚唔用閃成功既機會，配合is，真係超級好用!!!

[sannaso]

講得好!根本17-55就係L鏡,無論造工,構造,用料,價錢.....只因佢係EF-S鏡先無紅圈,為左無紅圈而唔買佢,簡直浪費....

兩枝我曾同時擁有過，機是40d。我會選24-105。
畫質:24-105color會柔和少少。立體感多啲，畫質會好啲啲。
24-105焦距好好用，影戶外和好天時好好用，當您上FF機唔需要換鏡。如果你需要大光圈和wide angle便選17-55。
