我昨日買了A80,諗住試下玩淺景深啦~~
但部機zoom完3倍光學變焦後,對焦唔到15cm以內的主體.....就算用埋微距加腳架都對唔準個焦點......試過用手動...但行bar最多都系到20cm,冇得再細
請問A80係咪zoom完後係對唔到近野ga???
我之前用個部olympus3030都可以zoom完再對焦玩淺景深.......點解A80唔得???

Yes most of the DC can't do marco focusing after full zoom. I remember there is only few DC can do that...

你試下將鏡頭zoom到最wide，同時開了微距功能來作近距離拍攝。希望幫到你啦！

This is normal for A80. The closest focus distance is difference at the wide end and the long end. If you want to get closer at the long end, you have to use the optional close-up filter or reverse mount a standard lens on it.

首先多謝各位的幫助.我又有個疑問,如果將鏡頭zoom到最wide，同時開了微距功能來作近距離拍攝,咁個景深係咪應該唔夠用完zoom之後再近攝的淺呢??(以我理解係因為焦距唔夠長,唔知我有冇理解錯呢?)
咁如果係真的話,有乜方法可以玩"勁"淺景深呢??唔通真係要加鏡先得??

If your goal is shallow DOF, you might place the subject very close to the camera, and increase the subject-to-background distance. But it really depends on what you are trying to photograph.

如果用在單鏡機上，你的理論是沒錯的。但實際上一般dc都很難做到淺景深的，所以我建議你在另購外置鏡頭前，最好先找朋友的來試清楚才買。很有可能加了外置鏡頭亦不附你的要求。
