各位C-Hing: 小弟用Canon 40d,想入支wide angle,但不要Canon 10-22mm,因為可能好快上5DII,有無CHING 可以幫下我俾下意見細佬 唔該哂 !!Thank you!!

Sigma 12-24 okay?

[nwt15]

17-40 or 16-35...

Even if u are using FF, u can still use 10-22 with your 40D

If u really want wide to ultrawide in aps-c camera, 10-22 is a very good choice

I use Sigma 12-24mm with 50d, It is just ok for the sharpness. But I find some Ching use with 5D MKll, it's totally a different Len. It's very sharp and very wide. 如果日後會上FF, it's a good choice.

多謝幾位意見,我諗我會入Sigma 12-24mm ,Thank you!!

Sigma 12-24, very poor quality as compared to 10-22 for APS-C Canon!

市面有售唯一最廣角的FF鏡頭。

[PROGEARTEAM]

SIGMA 12-24 , it's a good choice for 5d2

[Panda1802]

那Tokina 12-24 f/4 and Tamron 10-24 也不錯.

[王迦南]

這兩支都不是FF鏡，不能上無敵兔。

基本上，除非你不需要超廣角，否則，Sigam12-24是唯一選擇。

I use EF 16-35mm f/2.8 L II USM... very sharp and good.. but also expensive...

if you will upgrade to FF.. probably it was a good lens for you..

[王迦南]

EF 16-35mm f/2.8L II USM的最闊視角是108度10分，價約$11,xxx。

12-24 f4.5-5.6 DG HSM的最闊視角是122度，價約$5,xxx。

如何取捨？按各人的拍攝需要及財力吧！
