你買左sigma , 一定會心思思紅圈.

17-50好真的很好.有2.8又有os,又有lock鍵.又有hood送.性價很好.不過佢無對焦窗,仍然係對焦環設計,無得full 手動,同埋我兼佢唔係內變焦.如果唔係有個師兄想要我都一直會用,唔放住,之後我而家買左17-40,雖然得f4,又無is,但我一般都係keep住安全快門咁影,有時就用iso就下囉,總來講我覺得17-50很好,很利,好似好過17-40少少,少少咁多啦,不過我個人like內變焦既lens為主,又加上係原廠之人,所以始終都係心思思買返支紅圈來玩下.

好似係17-40稍勝喎!

[speeeed]

YES

[swhsimon]

I read website compare betw them.

conclusion:
a. Canon Resolution better a lot
in all f & mm range

b. IS for Wide Angle ..is it really necessary.

Thank you for all!

我是新手，用梗60D+sigma17-50, 我都覺得佢好好，色靚，做到好靚波波散景。但我最近入左支小小白，發覺紅圈真係唔同，canoncD色係自然D（心理問題），所以我都決定放左支sigma 入支17-40.

s17-50

距離可以取決於自己行遠行近, 自己容易控制;
但光圈就不能...

[speeeed]

我同你一樣

Canon 係好d,
不過17-40就未必好o岩,

17-40 係APSC度, 唔係wide only, 係wide to standard, 所以防震有一定既用處,

17-40 係F4 時, sharpness 麻麻, 可以比美18-55, 即係叫你收一級, 收到5.6咁用,再配合無is! 你當然可以話唔介意支鏡sharp唔sharp既,

如果好鍾意L, 就快d入啦!
