師兄~ 17-40L响5D上都係一支wide鏡，但有無c hing玩過支SIGMA，又或者擁有過呢兩支呢？我有個朋友之前用Canon 5D轉左會D700，但都係重覆買番呢支鏡？呢支鏡真係咁好，我係Canon Fans，我都擁有17-40L，但SIGMA呢支全未接觸過，呢支鏡ok ma？FF有12mm廣角會黑角ma?但景觀咪比17-40L正好多囉！！！

12-24 影景都唔錯嘅,不過色水就一定無 17-40 咁好,睇你要乜囉

12-24 @ 12mm







17-40 @ 17mm

唔該shawnchau C hing~ 17-40L我已經有，不過d魔鬼朋友常常引我買呢支，其實我仲有部40D比左我老婆用，鏡用Tokina，但我諗都想放左支Tokina佢[ 因不FF & DX能兩用 ]，都想入手支12-24比我取代17-40L比番我老婆部40D度，無問題但好似有d嘥錢咁？shawnchau C hing你兩支都擁有？入手咩價？二手入手ok ma？

我賣咗枝 17-40mm f/4 L，跟住買枝24mm f/1.4 L，好滿意！定焦好正嫁.............

shawnchau 兄 thanks for you sharing

12mm 同 17mm 真係兩個世果的事，絕對唔可以輕看那 17mm 打後的每1mm的寬闊

sigma 12-24 光圈較細，不過影景多，所以腳架必備吧！

12-24 FF APS-C 兩用係佢好處,不過如果可以問人借嚟試吓先就最好,因為我唔肯定我枝係 bad copy 定係佢解像力應付唔到 APS-C 嘅 pixel density , 我用喺 5D 都OK sharp ,縮咗圖同 17-40 睇差唔多,但係我一用落 350D 就散到PK, 點收光圈都好似完全唔中焦咁(呢個point都周不時有人講,所以如果人用 APS-C 多數推介 tokina 12-24 / EF 10-22 .

如果火ken ching 可以問咗fd嚟試吓喺FF 同 APS-C 影出嚟sharpness PQ會唔會差好遠先入手會保險好多^^ 呢枝嘢同普遍鏡頭一樣升咗幾多吓,我兩三年前買 $4400 而家好似要起碼 $5300 囉,同埋無乜留意二手幫你唔到@@

如果可以最好買一手,同埋帶埋notebook 去,因為我枝係右邊 sharp 過左邊(應該係光軸偏移咗,不過我唔排除正常邊位應該係唔sharp,我有一邊sharp係good copy 因為無 fd 有得比較 lolzz) , 攞過去 sigma cal , 佢 send 咗返日本三個禮拜後我攞返佢話無得整@@ 所以一手你影完用 notebook 100% 放大睇會穩陣好多,你機身個mon 睇唔到啲乜嘢出樣 ^^"

<<350D 就散到PK>> 咁就 5D2都唔掂了，因為5D2個 pixel density 應該同 350D 係同級的 ！！

[shawnchau]

所以我都唔夠膽肯定係機問題定鏡問題,所以建議火ken ching 如果可以嘅話問 fd 借咗嚟試吓先 :)

I think I'm lucky enough to get a good copy

Agree Ching said, need to check carefully before pay or have a reliable shop they are willing to exchange in 10 days if any issue found.

咁初步結論 12-24 真係唔適合用喺 APS-C , 完全同 EF10-22 , sigma 10-20 , tokina 12-24無得比, 最好睇吓火ken ching 平日攝影重心係邊部機再作決定, 如果FF 用多都係留返 17-40就算喇:D

聽到之後好心傷，之前唸過買s12-24日後上FF有勁闊angle玩，點知……
