50D用, 17-40L 定係 24-105L好? 用1.6 crop 機,24個wide差少少. 除左焦距範圍,表現, 成像上有什麼明顯分別?

[gary_che]

如果影景為主的話，就一定係17-40L
影人像為主或近攝的話，影花一流，就揀24-105L
如果係我的話，就一定係揀17-40L，影風景照就真係一流，合晒我口味

I will definitely choose 24-105 for its zoom range and IS function. Regarding of the quality, 24-105 will be much better on portrait and close up shots. 17-40 is a very good sharp Len, but really limited for taking landscape and big group photos. Between its really depends on your use.

要睇返你自己需要d乜 / 會影乜, 其實兩枝都係好鏡.

ching, 如果我係你用50d, 呢兩支都唔會買, 我會買17-55 f2.8 is usm, 呢支簡直係1.6x機既標準變焦鏡皇, 係1.6x機既恩物, 有齊大光圈, is, usm, 焦段夠實用, 又夠wide(17x1.6=27mm), 24-105(=38.4-168)用o係50d度唔夠wide又唔夠tele, 兩頭唔到岸, 24-70又貴又重, 唔用直度實出事, 請三思~

師兄17-55枝鏡唔同級數，無得比較。

[kenjikenji]

24-105L 支鏡唔得，wide angle　時變形得很利害，如你影過結婚禮堂，　你就會一清二楚，可能不是FF 會好回點，　但這價錢好像不值，　只是買個心理的"L"字而已

[tcfreeman]

the optic about 17-55f2.8, so close to the L lens, if i were you select this len for cf body, when move to ff body god known!

[TONG3]

任何鏡在wide angle時都會變形，並不是24-105的專美，除非用移柚鏡，不過你講得好，咁貴的價錢可能係買個《L》字。

喂,小三元都話貴???? 我無話好說咯!!!

[hongdonald]

對我來說已很貴 我連窮人三寶也買不起呢...

To 呀你爸爸,

c-hing 你做咩事呀？個個 post 都出一個？你好唔想人買 50D 咩？我用 40D 都唔知你想點！?_?

剛入手50D 成象很好,按鈕方便! (可能我支鏡靚~~~~)

[Ref54]

用於50D,我建議用EFS 17-55 2.8,因為焦段實用。
24-105 4L在FF機來講可以話係支好嘅天涯鏡,但用於APS-C就有點力不從心。
不要被一個"L"字誤導,L只係Luxury咁解,冇L字唔一定代表係差,EFS10-22那支wide鏡就係一支非常好嘅鏡。
