買 Canon EF 17-40mm f/4.0L or Sigma 17-50mm F2.8 EX DC OS HSM

去旅行要影日與夜, 人,景,物點好?

Thank~

Sigma 17-50 OS尚未上市，具体情况未知。你可以做白老鼠，上市就买。也可以看看其他白老鼠的反应。或者买被称为“伪红圈”的无论是做工、机械性呢个、耐用性还是光学素质都算得上很好的17-40L。

SIGMA 17-50 OS 好D
日夜能兼顧, 大光圏又有OS, 解像力更好

多謝 wllui ching~
or buy NEX 3/5 wahahahahah~ 唔洗咁重~

我會揀17-50 os...一來光圈大d...二來有os...!

nex 3/5係另外一樣野...如果要輕便當然好...但我係信影出黎一定係sigma支鏡靚d!~

Thank you Daph~
