 sony 30mm/F2.8 OR sigma 18-50/F2.8?? 請入黎比D意見 Post time: 6 月 1 日 |

本人想買支光圈唔太細又有marco既鏡。原本諗住睇中左sony 30mm/F2.8，貪佢平、光圈f2.8同有marco，上網諗住睇多D意見既時候睇到人講sigma 18-50/F2.8，好似好正咁，但有好多人都話sigma鏡多數要cal鏡。
其實我想要一支sharp同有marco既鏡。
現在想請教下各位邊支鏡岩我用途多D??
主要用途：
室內影物件、食物、寵物，最後先係人像。
唔該各位師兄解答一下。Thank all

sigma 18-50/F2.8 放大率只有1:4.1唔係marco鏡
唔好以為鏡身寫住marco就可以代替真正marco鏡.....

開頭就係覺得抵所以睇中30mm/F2.8，但又因為自己貪心，想買支鏡又要有marco，又要比我zoom下，又要個光圈唔好太細，所以先睇到sigma 果支18-50/F2.8，仲要上網睇人地D相影出黎D色水好正(個人覺得)，但又睇到sigma好多鏡都話會走焦，同埋怕影出黎唔sharp，所以先想問下大家意見。

建議自己試清楚先，不是每個人都須要1:1的放大率的。
一般玩下好少會影到咁近的。

其實我個心都偏向sigma 18-50/F2.8，但聽見會走焦，就有D驚。
同埋想問下邊到會有sigma既鏡可以試呢??(即係好似sony shop咁)

好多人話Sigma鏡用在Canon機好易走焦,不過我自己未試過
但就試過Sigma鏡用在Sony機唔覺特別容易走焦
當然如果用入門機在很暗的環境就算用Sony鏡都有機會走焦
但我用A850在相同環境,唔理用Sony定Sigma鏡都唔會走焦

30mm微距鏡好難影1:1的.咁短焦距會幾乎貼住主體,你買定支微距閃服侍佢都得喇.

By what your objective of buying the lens, I would say you search for a Minolta 50mm f2.8 Macro. This can give you a 1:1 Macro function, good for portrait (if you are using APS-C DSLR), and bigger aperture. The quality of the lens is no doubt very good too. Second hand price is around $2,000. You can also go for a Sony 50mm f2.8 Macro lens, which is of course more expensive.
Sigma 18-50 f2.8 does not have much problem in focusing when used in Sony DSLR. Yet, the macro is not really macro at all.
Sony 30mm 2.8 Macro is a true 1:1 macro lens. But its shortest focusing distance is really very short. You have to be very close to the object to take a 1:1 macro photo, which is meaningless as it will obstruct enough light for exposure. Its building quality is not good too, although its price is very low for a brand new one.

多謝各位既意見，好詳細同好有用。
聽咁多位都話sigma 鏡用係sony 機唔會走焦，咁我諗我會揀sigma 18-50/F2.8喇~~
