為何A7R連ISO-25600都可以贏A7S?

Aug 21st 2014, 16:09

---------------------------------------------------------------
1200萬對比 3600萬，3倍的畫素差異，為何A7R連ISO-25600都可以贏A7S?

A7R縮圖到跟A7S一樣的1200萬素，不管是雜訊、細節，A7R都贏A7S。

A7S細節輸A7R還可以理解，畢竟3倍畫素差異。

但雜訊輸就真的搞不懂了? 3倍畫素差異的優勢...?

之前比較就知道A7R-ISO-12800贏A7S了，但大家都說A7S真正的實力是從25600開始...???

我一開始也相信A7R-ISO25600應該會輸A7S，因為我猜A7R的ISO-25600應該是擴展吧?

A7S原生贏A7R擴展，理所當然?? 但沒想到A7R-ISO-25600還是贏A7S，真的是意外了

已經買A7S的用家應該會很失望吧? 買一台寄以厚望的高ISO神機...?

細節輸就算了，結果高ISO表現還如此不堪...
