如果係同一支鏡頭之下, 呢個理解係正確, 但都唔關ISO事
而且呢樣野FF同M43/APSC無得比,
因為你要達成呢個條件, 要用同一支鏡頭, 視角一定唔一樣
睇錯MP3
This means that a Four Thirds camera with a 50mm f/2 lens at ISO100 should produce a JPEG of the same brightness as a Full frame camera with a 100mm f/2 lens at ISO100 and, set to the same F-number and shutter speed, even though its smaller sensor means it is receiving 1/4 as much total light.
M43同FF 重疊面積入光量係一樣, 唔會話邊一個光d
你想講想既M43 同FF ISO 係唔同, 完成係錯concept
