各師兄...我想入一支新鏡!去旅行影風景多的!有咩好提議!!!
自己比較喜好17-40F4L

[Taikin]

用緊FF機?

[cktommy]

我依家用緊450D~~遲下轉7D!
未打算上FF住!有咩好提議

[homankop]

17-40+70-200

[lamlam10]

用緊x1.6機買17-40影景唔夠wide
考慮下買tokina12-24 or 11-16
Canon 10-22

唔上ff, 17-55 is好好多, 多條紅圈真係咁重要?

[cktommy]

我都知17-55好多人用過都話好..但係好貴呢!仲要係EF-S

[ltm852]

But 17-55 is the only EF-S len which has F2.8, also the quality is near 'L' class len, highly recommend!

[kenanet]

真係甘堅？有無比較WEBSITE?

[petercyc]

用咩機, 配咩鏡. 唔上FF, EF完全冇優勢. 相反EF-S可以更輕更靈活. 俾多少少有IS, 大一級光圈. WHY NOT?

[kenanet]

甘ef-s 17-55 係crop機係咪都要乘大1.6呢？

[nofeel]

要乖大1.6 而且好重

[hkstc]

17-40內變焦唔使伸縮，靚野

[Taikin]

10-22
T116
S10-20 遲d有8-16

一支過就c15-85

影景就梗係要夠wide
18起跳都唔夠wide..

我都唔建議你買，
1. 你提到唔會上FF住，咁EF同EF-S根本無需考慮，而且EF-S鏡都唔差
2. 17-40X1.6，即係變成27X64，影風景可能會差一D
3. 再要睇埋你本身有支咩鏡，如果你跟KIT鏡，17-40同你支KIT都分別不大
4. 小弟覺得，雖然大光圈唔係大曬，但恆定F2.8肯定好過F4，至少寬容度大
5. 依家副廠鏡既質素都很好，都拍得住正廠

所以，
我建議你買支再WIDE D既鏡，
唔好俾條 "紅" 線遮住你對眼！
