各位師兄及前輩,
以上兩支鏡那一支用于30d較適合, 會有黑角現像嗎??

kongs,

both lens can use in 30D, but if you will go for FF then 16-35 can be used on FF body.

For back corner, you will not have problem for 16-35 as this len is for full frame body so you just use the centre part of the len on 30D.

For 17-55 you will not find black corner but in certain situation you will have some light fall off which is not very noticeable unless you use 17mm at 2.8 apeture and on a sky or on a unique colour situation otherwise it would not be a big deal.

I have 17-55 and 17-40 but don't have 16-35, on 5D (I have this, 17-55 can't be use on 5D) even the 17-40 will have black corner but depends on how you use it.

So it depends on what range you would like to have, black corner is not a big deal some software can remove it. Both lens are good, you won't be wrong to buy either one.

所有佳能鏡用在 30d 上都唔會有黑角。

我較喜歡後者EF-S 17~55mm f2.8 IS USM，焦段較好用，大光圈加防震，弱光拍攝無敵！
