咁請問各師兄有冇用過sigma 嘅70-200 f2.8 EX APO NSM DG,請比啲意見,因為佢同小小白价錢差不多,但有F2.8,都幾吸引,所以小弟想買再加 extender x2.0,請各師兄比啲意見,因為本人DSLR的新豬肉,請多多提点.

+ 2 x QUALITY 唔好,係+ 就加SIGMA 1.4x,正.

講你聽呢支鏡QUALITY 超好,收到4 會好過小小白,絕對直得買,如果你唔嫌大

請問 2X 唔好的地方是否光圈變成 F5.6 ? 或有其他的問題? 在wedsite上很少人談論這支鏡,多數是講小白及小小白, WHY? 是否個個用得這樣的 tele-zoom 都是有錢人?

70-200 f2.8 EX APO NSM DG
APO 70-300 F 4 / 5.6 SUPER MACRO
以上两枝鏡那一款值得投資。

I had once used the lens, I think it was ok in quality and speed. However, when I used it with Kenko 2X extender it could not AF properly with EOS 10D, the lens hunting all the time. However the same combination (ie Sigma 70-200 + Kenko 2X) worked fine with EOS 5.
