今天早上拿到一隻 iPhone 7 Plus
現場簡單測試都沒發現甚麼異狀,不過因為現場不太可能測試太久,
只是簡單檢查所有功能而已
回來之後針對相機的功能仔細地玩一下,就發現一倍跟兩倍切換的時候怪怪的
兩倍拍起來之後就是沒這麼銳,照片感覺就是被強迫數位放大的那種發散的感覺
所以我在猜第二顆鏡頭並沒有被切換到
所以簡單做了個實驗,果然把望遠的鏡頭擋住居然還是可以拍兩倍
〈問題排除〉
感謝下方的許多資訊,所以總結一下結論在這邊給有相同疑問的人參考
會出現這種狀況的原因在於相機的曝光計算
環境光源購亮的強況下,相機就可以在任何距離啟動“光學”兩倍
但是光線不足的情況下就變成數位變焦模式
原因是廣角鏡頭光圈f1.8比較大,望遠的光圈小只有f2.8
加上沒防手震的原因,所以低光不讓使用真正的望遠鏡頭
看起來是折衷的設計,也代表夜間無光學兩倍可用,看來下一帶應該會補足這問題...
